CAT823 Datasheet PDF - Catalyst

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.
