Low Power 5V μP Reset
ASM1812
rev 1.4
February 2005
Application Information
Operation - Power Monitor
The ASM1812 detects out-of-tolerance power supply
conditions. It resets a processor during power-up, power-
down and issues a reset to the system processor when the
monitored power supply voltage is below the reset threshold.
When an out-of-tolerance V
CC
voltage is detected, the
RESET signal is asserted. On power-up, RESET is kept
active (HIGH) for approximately 150ms after the power
supply voltage has reached the selected tolerance. This
allows the power supply and microprocessor to stabilize
before RESET is released.
