DESCRIPTION

The CAT823, CAT824, and CAT825 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 140ms; 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 and CAT825 also provide 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.
