Application Information

Operation - Power Monitor

The ASM1233D-L/1233D/1233M detects out-of-tolerance

power supply conditions. It resets a processor during power-

up, power-down and generates a reset to the system

processor when the monitored power supply voltage is below

the reset threshold. When an out-of-tolerance VCC voltage is

detected, the RESET signal is asserted. On power-up,

RESET is kept active (LOW) for approximately 350ms after

the power supply voltage has reached the selected tolerance.

This allows the power supply and microprocessor to stabilize

before RESET is released.
