ADM699ANZ

ADM699 supervisory circuit provides power supply monitoring and watchdog timing for microprocessor systems. The ADM699 features an identical monitoring circuit as in the ADM698 plus an additional watchdog timer input to monitor microprocessor activity. The RESET output is forced low if the watchdog input is not toggled within the 1 second watchdog timeout period. Typical application includes microprocessor systems, computers, controllers, intelligent instruments, automotive systems and critical MP power monitoring.
