1996 sep 04 5 philips semiconductors product speci?cation light position controller tda3629 functional description the device is intended to control the elevation of the light beam of a head light of a passenger car. the driver can control the elevation of the light beam by rotating a potentiometer on the dashboard (the setting potentiometer). the device adapts the elevation of the light beam by activating the control motor. the elevation of the head light is fed back to the device by a second potentiometer (the feedback potentiometer). this feedback potentiometer is mechanically coupled to the motor. the device operates only when the supply voltage is within certain limits. the device is switched off outside these boundaries. the under voltage detection detects whether the supply voltage is below the under voltage threshold. the motor will not be activated when this occurs, but it remains short-circuited by the output stages. the over voltage will switch off the total device when the supply voltage is higher than the over voltage threshold. a thermal protection circuit becomes active if the junction temperature exceeds a value of approximately 160 c. this circuit will reduce the motor current, which will result in a lower dissipation and hence a lower chip temperature. this condition will only occur when the motor is blocked at high ambient temperature. a detection of a broken wire of the slider of the setting potentiometer is included because it will be connected to the device by a wire several meters long. this detection circuit prevents the motor from rotating when the wire is broken. in this event the brake will remain active. the protection of v set to v p circuit prevents the motor from rotating when the voltage at the v set input is above the threshold value. this can be used to detect whether the wire from the slider of the setting potentiometer is short-circuited to the battery line. a protection of v set short-circuited to ground is also present. the motor will be stopped if v set becomes lower than the threshold level. the shaded areas in fig.4 represent the parts where the short-circuit protection stages are active. figure 4 shows that a position of 0 mm can not be reached, neither can a position of 100%. the minimum position that can be reached depends on the battery voltage v b , although the maximum position does not. the device is protected against electrical transients which may occur in an automotive environment. the device will shut off when positive transients on the battery line occur (see figs 7 and 8). the motor will not be short-circuited in this event. the flyback diodes, illustrated in fig.1, will remain present. the state of the output stages at the moment when the transient starts is preserved by internal flip-flops. negative transients on the battery line (see figs 7 and 8) will result in a set short-circuited to ground fault detection, because it will result in a voltage at the setting input which is below the short-circuited to ground threshold. the device however discharges the electrolytic capacitor during these transients. it will stop functioning when the resulting supply voltage becomes too low. fig.4 conversion gain. handbook, halfpage mge635 100 position (%) 0 0 v set(min) v set(max) v set (v) v b
1996 sep 04 6 philips semiconductors product speci?cation light position controller tda3629 the timing can be divided into several parts starting from a steady state (see fig.5, the starting point, and fig.10 for the application diagram): in this state (until t 1 ) a large reference current is active, indicated by the dotted lines. when the setting potentiometer is rotated (started at t 1 and indicated by v set ) and the input current i set becomes higher than the reference current i ref (at time t 2 ), the motor will start and the input current will decrease. at the same time the reference current is switched to a low level. during rotation of the motor the input current will decrease until it becomes lower than this low reference current; this occurs at time t 4 . at this time the brake becomes active, the motor will stop and the reference current is set to the higher value. the brake is realized by short-circuiting the motor. in general: this system does not use a linear adaptation strategy but an on-off strategy. this results in high accuracy and low noise sensitivity. the brake is active at any time during normal operation when the motor is not active. the polarity of the feedback potentiometer should be such that the voltage at the slider of the feedback potentiometer increases when out1 is high and out2 is low. fig.5 timing diagram. handbook, full pagewidth v set v fb i set i ref absolute motor current v2 v1 v1 0 0 t 1 t 2 t 3 t 4 time mge636 v2

1996 sep 04 9 philips semiconductors product speci?cation light position controller tda3629 notes to the characteristics 1. steady state implies that the motor is not running (i m = 0) and v set = v fb = 0.5v p . 2. this is only valid when the temperature protection is not active. 3. d v set is the difference in voltage on the set potentiometer between the situation when the ground wire is interrupted (v set, br ) and voltage on the set potentiometer during normal operation (when v set = 0.17v b = 2.72 v). the conditions for this test are: r set = 20 k w ; v b = 16 v; d v set = v set, br - 2.72 v; see fig.6. quality specification the quality of this device is in accordance with snw-fq-611 part e . the numbers of the quality specification can be found in the quality reference handbook . the handbook can be ordered using the code 9397 750 00192. fig.6 conditions for the test of note 3. the 170 w , 830 w and 390 w resistors form the setting potentiometer in its worst case position. the given situation (combination of v b , r set and the position of the set potentiometer) forms the worst case situation. the given maximum of d v set guarantees that any other module, connected to the same set potentiometer, will not start to activate its motor, when its motor switch-on level is higher than 0.01v b (r set 3 20 k w ). handbook, halfpage mge637 r set v set, br + v b battery ground 830 w 390 w 170 w remainder of module ground wire not connected + -

1996 sep 04 11 philips semiconductors product speci?cation light position controller tda3629 application diagrams and additional information two possible application diagrams are shown. the first (see fig.9) shows the best case: the lowest component count. the second (see fig.10) shows additional components which may be necessary. two capacitors are added to meet emc requirements (one on the v p pins, the second one between the set and feedback input pins). a third capacitor has been added across the motor to suppress current spikes. the given values of these capacitors have to be optimized by experiments carried out on the total application. the resistors do not have to have the same value. the voltage hysteresis is set by means of r set . the resistor in the feedback input line (r fb ) is present to limit the current during the transients as illustrated in figs 7 and 8. this resistor should have a value larger than 2 k w . r set can be chosen freely but must also be larger than 2 k w . a diode is placed in series with the supply line in both applications to protect the device from reverse polarity switching and from damage caused by pulses 1 and 3 in figs 7 and 8. in the present application a varistor is included in the motor. the electrolytic capacitor of 47 m f should have a very low esr, for instance as low as 5 w at a temperature of - 40 c. an extra ceramic capacitor (approximately 100 nf) parallel to it is obligatory when this can not be guaranteed. fig.9 best case application diagram. handbook, full pagewidth mge640 input stage short-circuit supply broken wire protection - over voltage - under voltage - temperature windows and comparators v p v p1 v p2 v p out1 output stages out2 set 1 k w 2.2 k w fb i set r set r fb i set tda3629 + v b + v b + v b v set + - v fb + - m v m + - mechanical transmission 43 v 47 m f i m i ref

1996 sep 04 13 philips semiconductors product speci?cation light position controller tda3629 table 1 duration of the pauses the maximum allowable dissipated power p is then 0.77 w during the motor active periods in the event of a dip8 package being used. dissipation pulses due to starting and stopping the motor can be ignored because of their short duration. this maximum allowable dissipated power implies that the maximum continuous motor current ( ? i m ? ) is approximately 250 ma during the motor active periods when the supply voltage v p is 13 v. the maximum allowable dissipated power p is 0.67 w during the motor active periods in the event of a so16 package being used. this implies that the maximum continuous motor current ( ? i m ? ) is approximately 220 ma during the motor active periods when the supply voltage (v p ) is 13 v. t amb ( c) pause (s) <95 60 95 180 95 to 105 300 fig.11 thermal transient test. the duration of the pause depends on the ambient temperature, see table 1. handbook, halfpage mge642 active motor inactive pause 8 s 4 s time (s) stereo operation the default application will be when two modules are driven by one set potentiometer. one module controls the left head light, where the other one controls the right head light. each module is connected by three wires: the battery line, the ground line and the set input wire. this can result in two additional fault conditions: from one module the battery line or the ground line can be broken, when the other module is still connected. assume that the left one operates normally, where the right one has a fault. the setting potentiometer will have extra loading when the battery line is broken. this will result in a lower voltage at the wiper of the setting potentiometer. thus the left module will start to regulate until a new equilibrium is reached. the amount of extra loading can be influenced by the external series resistor in the set input. these fault conditions and their implications should be considered when the total application is designed. test diagram all parameters in chapter characteristics until this section are measured at t amb = 25 c and are tested at each device using the test set-up of fig.12. the only exceptions are parameters supply current (motor active) and output voltage (motor output) where the 1 k w output resistor is replaced by an appropriate current source.

1996 sep 04 15 philips semiconductors product speci?cation light position controller tda3629 immunity to narrow band electromagnetic disturbances test procedure g eneral information the immunity is measured using a test procedure, which is derived from the draft international standard iso/dis 11452 , parts 1 and 7, submitted for circulation 1992 june 14. the test is carried out using a printed-circuit test board in a test set-up, which is illustrated in fig.13. the circuit diagram of the test board is shown in fig.14. the physical layout of the test board is shown in figs 15 to 17. p reparation of test the ic under test is mounted onto the printed-circuit test board. the printed-circuit test board is mounted into the faraday cage (rf-shielded 19 inch-rack) and connected to the test equipment as shown in fig.13. one of three rf voltage injection points has to be chosen for injection, while the others have to be connected to passive terminations. the injection into the control loop via input rfc is shown in fig.13. after the set-up is completed, the feedback voltage is selected by the appropriate setting of a jumper in the jumper field j1 (see fig.14) and the battery voltage is switched on. with no rf voltage injected the correct operation of the system is verified by turning the set potentiometer (see fig.13) left and right (or vice-versa). the outputs out1 and out2 will switch to on-state (absolute differential voltage v diff = 3 to 5 v dc) in both turn directions. if the device under test functions correctly, the potentiometer is set to a position where the absolute voltage difference between the slider connection of the potentiometer and the jumper j1 is less than 5 mv. after adjustment, the absolute differential output voltage v diff has to be below 100 mv. having reached this condition the immunity test may be started. t est of immunity for the test of immunity the rf voltage is injected into the test board and v diff is monitored for degradation. v diff is degraded if its actual value exceeds the maximum value described in table 2. in the test routine the frequency is varied in steps from the start frequency to the stop frequency (see table 2). within each frequency step the level of injected rf voltage is incremented by steps to the maximum test level, which is specified in table 2. each step level is held constant for the dwell time. after the dwell time has elapsed, the degradation of the absolute output voltage is checked. if a degradation is detected it has to be verified, because the level setting may have an overshoot and the device under test may have a latching behaviour. the verification is achieved by switching off the power supply for 1 s after degradation is first detected. then the supply is switched on and the degradation is rechecked. if the second check also indicates a degradation, then the values of rf level and frequency are inserted into a data file for reporting. if the second check is negative the level is further increased. if no degradation occurs until the specified maximum test level is reached, the maximum level is recorded together with the frequency of that step. r ecommended rf- voltage setting procedure for a fast setting of the rf voltage to the required test level step it is recommended that the substitution method is used. this method sets the actual test level with respect to level values that have been filed in a pre-measurement. the rf source in the test set-up is built from a low-power rf generator and suitable amplifiers. in the recommended pre-measurement the rf voltage at the injection point is measured, while the signal generator outputs a constant voltage level (e.g. 100 mv). thus, the gain factor from the output of the rf generator to the injection point can be easily calculated. in the pre-measurement the rf voltage at the injection point is measured for each frequency step. dividing this measured voltage by 100 mv results in the gain factor for this frequency. all gain factors together with their frequency value are filed for use in the level setting of the immunity tests. in the immunity test routine, a required rf voltage test level at a frequency step is obtained by setting the rf signal generator to a level that is calculated by dividing the required rf voltage test level by the gain factor of that frequency. test conditions the test is carried out using the test procedure as mentioned before and under the conditions mentioned in table 2.

1996 sep 04 24 philips semiconductors product speci?cation light position controller tda3629 soldering introduction there is no soldering method that is ideal for all ic packages. wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. however, wave soldering is not always suitable for surface mounted ics, or for printed-circuits with high population densities. in these situations reflow soldering is often used. this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our ic package databook (order code 9398 652 90011). dip s oldering by dipping or by wave the maximum permissible temperature of the solder is 260 c; solder at this temperature must not be in contact with the joint for more than 5 seconds. the total contact time of successive solder waves must not exceed 5 seconds. the device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (t stg max ). if the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. r epairing soldered joints apply a low voltage soldering iron (less than 24 v) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. if the temperature of the soldering iron bit is less than 300 c it may remain in contact for up to 10 seconds. if the bit temperature is between 300 and 400 c, contact may be up to 5 seconds. so r eflow soldering reflow soldering techniques are suitable for all so packages. reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several techniques exist for reflowing; for example, thermal conduction by heated belt. dwell times vary between 50 and 300 seconds depending on heating method. typical reflow temperatures range from 215 to 250 c. preheating is necessary to dry the paste and evaporate the binding agent. preheating duration: 45 minutes at 45 c. w ave soldering wave soldering techniques can be used for all so packages if the following conditions are observed: a double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. the longitudinal axis of the package footprint must be parallel to the solder flow. the package footprint must incorporate solder thieves at the downstream end. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. maximum permissible solder temperature is 260 c, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 c within 6 seconds. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. r epairing soldered joints fix the component by first soldering two diagonally- opposite end leads. use only a low voltage soldering iron (less than 24 v) applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
