Shenzhen Meiyuxin Technology Co., Ltd. [ON Distributor] New Supply of CAT823RTDI-GT3 Monitoring Circuit Act Low MR/WD Quality Assurance! ! !

Description

The CAT823 and CAT824 provide basic reset and monitoringfunctions for the electronic systems. Each device monitors the systemvoltage and maintains a reset output until that voltage reaches thedevice’s specified trip value and then maintains the reset output activecondition until the device’s internal timer, after a minimum timer of140 ms; to allow the systems power supply to stabilize.

The CAT823 and CAT824 also have a watchdog input which can beused 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 also provides a manual reset input which can be usedto initiate reset if pulled low. This input can be directly attached to a push−button or a processor signal.
