♠ System Supervisory Voltage Reset with Watchdog and Manual Reset CAT823, CAT824
The CAT823 and CAT824 provide basic reset and monitoring functions for the electronic systems. Each device monitors the system voltage and maintains a reset output until that voltage reaches the device’s specified trip value and then maintains the reset output active condition until the device’s internal timer, after a minimum timer of 140 ms; to allow the systems power supply to stabilize.
The CAT823 and CAT824 also have 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 CAT823 also provides a manual reset input which can be used to initiate reset if pulled low. This input can be directly attached to a push−button or a processor signal.
