Low Power, 3.3V, μP Reset, Active LOW, Open-Drain Output
ASM1233A
rev 1.0
November 2003
Application Information
Operation - Power Monitor
The ASM1233A 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 V
CC
voltage is detected,
the RESET signal is asserted. On power-up, RESET is kept
active (LOW) for approximatley 350ms after the power supply
voltage has reached the selected tolerance. This allows the
power supply and microprocessor to stablize before RESET
is released.
