系统监控电压复位与看门狗和手动复位 System Supervisory Voltage Reset with Watchdog and Manual Reset
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.
