jun 27-06 sp6330 family: select ing a multi-voltage supervisor ? 2006 sipex corporation page 1 of 6 introduction the primary function of a microprocessor ( p) supervisor circuit is to ensure that the input supply voltage of a microprocessor is at proper levels during power up, power down and brownout conditions. if the input su pply voltage to a microprocessor is below its required operating rang e, it could cause code- execution errors, memory corruption and latch up. t he supervisor will constantly monitor the input supply to the microprocessor, and in the event this supply voltage falls below a certain threshold, the reset output will be asserted. many of today?s power products require several different voltage rails for powering various components. the microprocessor itself can h ave a separate core voltage and logic voltage. other components such as dsps, a sics and microcontrollers can have their own unique voltage requirements. to service this demand of monitoring multi-voltage systems, sipex has develop ed the sp6330 family. the sp6330 family is a series of multi-voltage supervis ors that offer monitoring of up to 4 separate supplies and are equipped with specia lized features. a complete listing of products and features are listed in figu re 4 at the end of this note. sp6332 typical applications circuit for monitoring 4 supplies with master reset, watchdog input and cmos reset output rstb v1 v2 v3 v4 i/o r2 r3 r4 r5 0.1uf 0.1uf 0.1uf 0.1uf mr sp6332 v1 1 v2 2 mrib 3 v3 4 gnd 6 wdi 7 rstb 8 v4 5 supplies up c4 c3 c2 c1 monitored to be solved by tm application note anp14 understanding and selecting a multi-voltage supervisor f eaturing the sp6330 f amily
jun 27-06 sp6330 family: select ing a multi-voltage supervisor ? 2006 sipex corporation page 2 of 6 inputs to the sp6330 family the sp6330 family has the ability to monitor up to 4 different voltages. two of these inputs (v1 and v2) have precision factory-set thresholds while the remaining two inputs (v3 and v4) are adjustable. v3 and v4 inputs allow the user to customize two additional supply thresholds by me ans of an external divider. the threshold for v3 and v4 inputs is 0.5volts. th e v1 input supplies power to the device and will have the highest threshold for a given application; its minimum operating voltage for is 1.8v. the factory set threshold range for v1 and v2 inputs are shown in figure 1. v1 typical threshold v2 typical threshold 4.625 2.313 4.375 2.188 3.075 1.665 2.925 1.575 2.625 1.388 2.320 1.313 2.190 1.110 1.670 1.050 1.580 0.833 0.788 figure 1 reset output ? rst or rstb the reset output can be either active low or active high depending on each device. the reset output can also be either open-dr ain or push-pull outputs. the open drain output requires an external pull-up resi stor to v1 for normal operation. the output high voltage (v oh ) of the reset output will be approximately equal t o the v1 input voltage. reset timeout period the reset timeout period is a built-in time delay f or the reset output. this timeout period is activated at power up or when all monitor ed voltages have risen above their respective thresholds. reset timeout period f or the sp6330 family is offered in four different time intervals: 50ms, 100ms, 200 ms and 400ms. the actual selection of timeout period depends on the applicat ions requirements of the system voltage settle time. the reset timeout perio d is used to ensure that all voltage rails and system clocks have stabilized pri or to executing code to prevent errors or data corruption.
jun 27-06 sp6330 family: select ing a multi-voltage supervisor ? 2006 sipex corporation page 3 of 6 manual reset input (active low) ? mrib the manual reset input allows the user to manually trigger a reset when monitored voltages are within tolerance. this is us eful for resetting the microprocessor when it locks up due to software iss ues. a push-button type switch can be used to allow the user to trigger a r eset externally. however, since a push button switch will bounce several times, a d ebounce element is needed. the manual reset input signal may also be a logic s ignal from an i/o line, watchdog timer or a power fail output. watchdog input ? wdi the watchdog checks for proper software execution. if the software locks up or enters into an unwanted, loop the watchdog timer ca n either assert a reset output or a watchdog output. some members of the sp6330 fa mily offer a watchdog output while others do not. the watchdog has an int ernal timer that has a typical watchdog timeout period of 1.6 seconds. if the watc hdog input (wdi) does not detect a transition within 1.6 seconds, a reset or watchdog output (wdo) will be generated. the watchdog input is usually connected to an i/o line for monitoring software activity. the watchdog circuit is useful f or generating a reset or non- maskable interrupt (nmi) signal during software loc k up conditions without human intervention. floating the wdi will disable t he watchdog feature. watchdog output (active low) ? wdob the watchdog output is active low and can be either an open drain or push-pull output. if wdi remains at ?high? or ?low? logic lev el for longer than the watchdog timeout period, the internal watchdog time r overflows and the wdob will be asserted. additionally, if the reset output is asserted due to an under- voltage condition, at any voltage input the wdob wo uld also be asserted. floating wdi will not disable the watchdog timer in devices with dedicated wdob output. power fail input (pfi) the power fail input is used to monitor the unregul ated dc voltage or other upstream voltage and to alert the system that a bro wnout or power failure is imminent. when the pfi input is tripped, it can inf orm the system to start a power-down routine in order to save important data before a reset output is asserted. the power fail input has a threshold of 0 .5v. by using a voltage divider the user can monitor any upstream voltage. connect pfi to v1 or gnd if not used.
