CAT809 Datasheet 3-pin Microprocessor Power Supply Supervisors

Manufacturer: onsemi

Overview: 3-Pin Microprocessor Power Supply Supervisors CAT803, CAT809,.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The CAT803, CAT809, and CAT810 are supervisory circuits that monitor power supplies in digital systems.

The CAT803, CAT809, and CAT810 are direct replacements for the MAX803, MAX809 and MAX810 in applications operating over the industrial temperature range.

These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 140 ms after the power supply level has risen above that level.

Key Features

  • a push.
  • pull RESET output (active LOW) and the CAT810 features a push.
  • pull RESET output (active HIGH). Fast transients on the power supply are ignored and the output is guaranteed to be in the correct state at VCC levels as low as 1.0 V. The CAT803, CAT809, and CAT810 are available in both the compact 3.
