Catalyst Semiconductor CAT824

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.

DESCRIPTION

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 pushbutton or a processor signal. 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 Operating Range from -40°C to +85°C Available in TSOT-23 5-lead and SC-70 packages For Ordering Information details, see page 13.
