Product Summary

The CAT823RTDI-GT3 system supervisory voltage reset provides basic reset and monitoring functions for the electronic systems. The device monitors the system voltage and maintains a reset output until that voltage reaches the CAT823RTDI-GT3 specified trip value and then maintains the reset output active condition until the device internal timer, after a minimum timer of 140ms; to allow the systems power supply to stabilize. The CAT823RTDI-GT3 also has a watchdog input which can be used to monitor a system signal and cause a reset to be issued if the signal fails to change state prior to a timeout condition. The CAT823RTDI-GT3 also provides a manual reset input which can be used to initiate reset if pulled low. This input can be directly attached to a pushbutton or a processor signal.
