FM812 - Microprocessor Reset Circuits

This page provides the datasheet information for the FM812, a member of the FM811 Microprocessor Reset Circuits family.

Datasheet Summary

Description

The FM811/FM812 is a low cost microprocessor supervisory circuit that asserts a reset if the power supply drops below a designated threshold or the manual reset pin is forced low.

Several different reset thresholds are available to accommodate systems operating at 3V, 3.3V or 5V.

Features

  • Feature.
  • Precision Voltage Monitor for 3V, 3.3V or 5V Power Supplies.
  • 6µA Supply Current.
  • 140ms Minimum Reset Pulse Width.
  • RESET Remains Valid with VCC as Low as 1.4V.
  • Active Low Manual Reset Input.
  • No External Components.
  • 4-Pin SOT-143 Package.
