CAT825 Datasheet | Catalyst Semiconductor

CAT823, CAT824, CAT825 System Supervisory Voltage Reset with Watchdog and Manual Reset Features - Automatically restarts microprocessor after Power failure - Monitors pushbutton for external override - Accurate under voltage system monitoring .. 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. The CAT823 and...
