DESCRIPTION The SP690A/692A/802L/802M/805L/805M are a family of microprocessor (P) supervisory circuits that integrate a myriad of components involved in discrete solutions to monitor powersupply and battery-control functions in P and digital systems. The series will significantly improve system reliability and operational efficiency when compared to discrete solutions. The features of the SP690A/692A/802L/802M/805L/805M include a watchdog timer, a P reset and backup-battery switchover, and power-failure warning, a complete P monitoring and watchdog solution. The series is ideal for applications in a……
