ADM8323 - Supervisory Circuits

General Description

The ADM8323/ADM8324 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems.

An on-chip watchdog timer checks for activity within a preset timeout window.

Key Features

  • Windowed watchdog, 8 timeout options 26 reset threshold options 2.5 V to 5 V in 100 mV increments 4 reset timeout options 1 ms, 20 ms, 140 ms, and 1120 ms (minimum) Manual reset input Open-drain or push-pull RESET outputs Low power consumption Specified over wide temperature range (.
  • 40°C to +125°C) Qualified for automotive.
