The SP690AEN-L is a low-power Microprocessor Supervisory with battery switch-over. The Microprocessor (μP) supervisory circuit integrates a myriad of components involved in discrete solutions to monitor power supply and battery-control functions in μP and digital systems. The series will significantly improve system reliability and operational efficiency when compared to discrete solutions. The features of the SP690A includes a watchdog timer, a μP reset and backup-battery switchover and power-failure warning, a complete μP monitoring and watchdog solution.
