Overview
ASM1832 3.
3 V mP Power Supply Monitor and Reset Circuit Description The ASM1832 is a fully integrated microprocessor supervisor.
It can halt and restart a “hung−up” microprocessor, restart a microprocessor after a power failure.
It has a watchdog timer and external reset override.
RESET and RESET outputs are push−pull.
A precision temperature−compensated reference and comparator circuits monitor the 3.
3 V, VCC input voltage status.
During power−up or when the VCC power supply falls outside selectable tolerance limits, both RESET and RESET become active.
When VCC rises above the threshold voltage, the reset signals remain active for an additional 250 ms minimum, allowing the power supply and system microprocessor to stabilize.
The trip point tolerance signal, TOL, selects the trip level tolerance to be either 10% or 20%.
A debounced manual reset input, PBRST, activates the reset outputs for a minimum period of 250 ms.
There is a watchdog timer to stop and restart a microprocessor that ...
