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.

FEATURES

Automatically restarts microprocessor after Power failure

Monitors pushbutton for external override

Accurate under voltage system monitoring

Brownout detection system reset for use with 3.0, 3.3, and 5.0 volt systems

Pin and function compatible with the MAX823/24/25 products
