ASM161 Datasheet Up Supervisory Circuit

Manufacturer: Alliance Semiconductor

Overview: .. October 2003 rev 1.0 ASM161 / ASM162 µP Supervisory Circuit Key.

General Description

The ASM161 and ASM162 are cost effective, low power supervisory circuits that microprocessor, microcontroller and digital systems.

If the power supply drops below the reset threshold level, a reset is asserted and remains asserted for atleast 800ms after VCC has risen above the reset threshold.

An improved manual reset architecture gives the system designer additional flexibility.
