Application Information
Operation - Power Monitor
The ASM1816 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 VCC voltage is
detected, the RESET signal is asserted. On power-up,
RESET is kept active (LOW) 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.
