The CAT823RTDI-GT3 provides basic functions for resetting and monitoring electronic systems. Each device monitors the system voltage and maintains the reset output until that voltage reaches the device's specified trip value, then maintains the reset output active condition until the device's internal timer, a minimum timer of 140 ms, has elapsed; to allow system power to stabilize.

The CAT823RTDI-GT3 also has a watchdog input that can be used to monitor system signals and cause a reset to be issued if the signal fails to change state before a timeout condition.

The CAT823RTDI-GT3 also provides a manual reset input that can be used to initiate a reset if pulled low. This input can be attached directly to a button or to a processor signal.
