ADM8323, Supervisory Circuits

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.

A reset signal can also be asserted by an external push-button switch thro
