The ADPL63164 low-power microprocessor (μP) supervisory circuits monitor single/dual system supply voltages from 1.575V to 5V and provide maximum adjustability for reset and watchdog functions. These devices assert a reset signal whenever the VCC supply voltage or RESET IN falls below its reset threshold or when manual reset is pulled low. The reset output remains asserted for the reset timeout period after VCC and RESET IN rise above the reset threshold. The reset function features immunity to power-supply transients.
The ADPL63164 has a ±2% factory-trimmed reset threshold voltage in approximately 100mV increments from 1.575V to 5V and/or adjustable reset threshold voltages using external resistors.
The reset and watchdog delays are adjustable with external capacitors. The ADPL63164 contains a watchdog select input that extends the watchdog timeout period by 128x.
The ADPL63164 is available with an open-drain active-low RESET output. The ADPL63164 is available in an 8-pin SOT23 package and is fully specified over the temperature range of -40°C to +125°C.
