1 motorola sensor device data photoelectric smoke detector ic with i/o and temporal pattern horn driver the cmos MC145012 is an advanced smoke detector component containing sophisticated very--low--power analog and digital circuitry. the ic is used with an infrared photoelectric chamber. detection is accomplished by sensing scattered light from minute smoke particles or other aerosols. when detection occurs, a pulsating alarm is sounded via on--chip push--pull drivers and an external piezoelectric transducer. the variable--gain photo amplifier allows direct interface to ir detectors (photodiodes). two external capacitors, c1 and c2, c1 being the larger, determine the gain settings. low gain is selected by the ic during most of the standby state. medium gain is selected during a local--smoke condition. high gain is used during pushbutton test. during standby, the special monitor circuit which periodically checks for degraded chamber sensitivity uses high gain also. the i/o pin, in combination with v ss , can be used to interconnect up to 40 units for common signaling. an on--chip current sink provides noise immunity when the i/o is an input. a local--smoke condition activates the short--circuit-- protected i/o driver, thereby signaling remote smoke to the interconnected units. additionally, the i/o pin can be used to activate escape lights, enable auxiliary or remote alarms, and/or initiate auto--dialers. while in standby, the low--supply detection circuitry conducts periodic checks using a pulsed load current from the led pin. the trip point is set using two external resistors. the supply for the MC145012 can b ea9vbattery. a visible led flash accompanying a pulsating audible alarm indicates a local--smoke condition. a pulsating audible alarm with no led flash indicates a remote--smoke condition. a beep or chirp occurring virtually simultaneously with an led flash indicates a low--supply condition. a beep or chirp occurring halfway between led flashes indicates degraded chamber sensitivity. a low--supply condition does not affect the smoke detection capability if v dd 6v. therefore, the low--supply condition and degraded chamber sensitivity can be further distinguished by performing a pushbutton (chamber) test. ? circuit is designed to operate in smoke detector systems that comply with ul217 and ul268 specifications ? operating voltage range: 6 to 12 v ? operating temperature range: -- 10 to 60 c ? average supply current: 8 a ? i/o pin allows units to be interconnected for common signalling ? power--on reset places ic in standby mode (non--alarm state) ? electrostatic discharge (esd) and lat ch up protection circuitry on all pins ? chip complexity: 2000 fets, 12 npns, 16 resistors, and 10 capacitors ? supports nfpa 72, ansi s3.41, and iso 8201 audible emergency evacuation signals ? ideal for battery--powered applications order this document by MC145012/d m o t o r o l a semiconductor technical data ? motorola, inc. 2001 t MC145012 p suffix plastic dip case 648--08 pin assignment 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 c1 c2 detect strobe v dd ired i/o brass te s t low--supply trip v ss r1 osc led feedback silver ordering information MC145012p plastic dip MC145012dw soic package 1 16 dw suffix soic package case 751g--03 1 16 rev 5 f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

MC145012 9 motorola sensor device data v dd (pin 5) this pin is connected to the positive supply potential and may range from + 6 to + 12 v with respect to v ss caution: in battery--powered applications, reverse--polar- ity protection must be provided externally. ired (pin 6) this output provides pulsed base current for external npn transistor q1 used as the infrared emitter driver. q1 must have ? 100. at 10 ma, the temperature coefficient of the output voltage is typically + 0.5%/ cfrom--10 to 60 c. the supply--voltage coefficient (line regulation) is 0.2%/v maxi- mum from 6 to 12 v. the ired pulse width (active--high) is determined by external components r1 and c3. with a 100 k ? /1500 pf combination, the nominal width is 105 s. to minimize noise impact, ired is not active when the vis- ible led and horn outputs are active. ired is active near the end of strobe pulses for smoke tests, chamber sensitivity test, and pushbutton test. i/o (pin 7) this pin can be used to connect up to 40 units together in a wired--or configuration for common signaling. v ss is used as the return. an on--chip current sink minimizes noise pick up during non--smoke conditions and eliminates the need for an external pull--down resistor to complete the wired--or. remote units at lower supply voltages do not draw excessive current from a sending unit at a higher supply voltage. i/o can also be used to activate escape lights, auxiliary alarms, remote alarms, and/or auto--dialers. as an input, this pin feeds a positive--edge--triggered flip-- flop whose output is sampled nominally every 1 second dur- ing standby (using the recommended component values). a local--smoke condition or the pushbutton--test mode forces this current--limited output to source current. all input signals are ignored when i/o is sourcing current. i/o is disabled by the on--chip power--on reset to eliminate nuisance signaling during battery changes or system power-- up. if unused, i/o must be left unconnected. brass (pin 8) this half of the push--pull driver output is connected to the metal support electrode of a piezoelectric audio transducer and to the horn--starting resistor. a continuous modulated tone from the transducer is a smoke alarm indicating either local or remote smoke. a short beep or chirp is a trouble alarm indicating a low supply or degraded chamber sensitiv- ity. silver (pin 9) this half of the push--pull driver output is connected to the ceramic electrode of a piezoelectric transducer and to the horn--starting capacitor. feedback (pin 10) this input is connected to both the feedback electrode of a self--resonating piezoelectric transducer and the horn--start- ing resistor and capacitor through current--limiting resistor r4. if unused, this pin must be tied to v ss or v dd . led (pin 11) this active--low open--drain output directly drives an exter- nal visible led at the pulse rates indicated below. the pulse width is equal to the osc period. the load for the low--supply test is applied by this output. this low--supply test is non--coincident with the smoke tests, chamber sensitivity test, pushbutton test, or any alarm sig- nals. the led also provides a visual indication of the detector status as follows, assuming the component values shown in figure 5: standby (includes low--supply and chamber sensitivity tests) ? pulses every 32.4 seconds (typical) local smoke ? pulses every 0.51 seconds (typical) remote smoke ? no pulses pushbutton test ? pulses every 0.51 seconds (typical) osc (pin 12) this pin is used in conjunction with external resistor r2 (7.5 m ? )tov dd and external capacitor c3 (1500 pf) to v dd to form an oscillator with a nominal period of 7.9 ms (typical). r1 (pin 13) this pin is used in conjunction with resistor r1 (100 k ? )to pin 12 and c3 (1500 pf, see pin 12 description) to determine the ired pulse width. with this rc combination, the nominal pulse width is 105 s. v ss (pin 14) this pin is the negative supply potential and the return for the i/o pin. pin 14 is usually tied to ground. low--supply trip (pin 15) this pin is connected to an external voltage which deter- mines the low--supply alarm threshold. the trip voltage is obtained through a resistor divider connected between the v dd and led pins. the low--supply alarm threshold voltage (in volts) (5r7/r6) + 5 where r6 and r7 are in the same units. test (pin 16) this input has an on--chip pull--down device and is used to manually invoke a test mode. the pushbutton test mode is initiated by a high level at pin 16 (usually depression of a s.p.s.t. normally--open pushbut- ton switch to v dd ). after one oscillator cycle, ired pulses approximately every 1.0 second, regardless of the presence of smoke. additionally, the amplifier gain is increased by automatic selection of c1. therefore, the background reflec- tions in the smoke chamber may be interpreted as smoke, generating a simulated--smoke condition. after the second ired pulse, a successful test activates the horn--driver and i/o circuits. the active i/o allows remote signaling for system testing. when the pushbutton test switch is released, the test input returns to v ss due to the on--chip pull--down device. after one oscillator cycle, the amplifier gain returns to normal, thereby removing the simulated--smoke condition. after two additional ired pulses, less than three seconds, the ic exits the alarm mode and returns to standby timing. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
MC145012 10 motorola sensor device data calibration to facilitate checking the sensitivity and calibrating smoke detectors, the MC145012 can be placed in a calibration mode. in this mode, certain device pins are controlled/recon- figured as shown in table 1. to place the part in the calibra- tion mode, pin 16 (test) must be pulled below the v ss pin with 100 a continuously drawn out of the pin for at least one cycle on the osc pin. to exit this mode, the test pin is floated for at least one osc cycle. in the calibration mode, the ired pulse rate is increased to one for every osc cycle. also, strobe is always active low. table 1. configuration of pins in the calibration mode description pin comment i/o 7 disabled as an output. forcing this pin high places the photo amp output on pin 1 or 2, as determined by low--supply trip. the amp?s output appears as pulses and is referenced to v dd etc. low--supply trip 15 if the i/o pin is high, pin 15 controls which gain capacitor is used. low: normal gain, amp output on pin 1. high: supervisory gain, amp output on pin 2. feedback 10 driving this input high enables hysteresis (10% gain increase) in the photo amp; pin 15 must be low. osc 12 driving this input high brings the internal clock high. driving the input low brings the internal clock low. if desired, the rc network for the oscillator may be left intact; this allows the oscillator to run similar to the normal mode of operation. silver 9 this pin becomes the smoke comparator output. when the osc pin is toggling, positive pulses indicate that smoke has been detected. a static low level indicates no smoke. brass 8 this pin becomes the smoke integrator output. that is, 2 consecutive smoke detections are required for ?on?
