The CAT824 provides a basic reset and monitoring function for the electronic systems. This 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 140ms; to allow the systems power supply to stabilize.
The CAT824 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 CAT824 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.
