ASM162 - uP Supervisory Circuit

Download the ASM162 datasheet PDF. This datasheet also covers the ASM161 variant, as both devices belong to the same up supervisory circuit family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • monitor power supplies in.
  • Edge triggered manual reset input single pulse output 49µS minimum MR disable period after reset CMOS/TTL logic or switch interface Debounced input Low supply current extends battery life.
  • 6µA / 15µA typ/max at 5.5V.
  • 4.5µA / 10µA typ/max at 3.6V Long reset period.
  • 0.8 sec minimum, 2 sec maximum Two reset polarity options.
  • ASM161: Active LOW, open-drain.
  • ASM162: Activ.
