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 power-
supply 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 automotive systems, computers,
controllers, and intelligent instruments. All designs where it is critical to monitor the power
supply to the P and it’s related digital components will find the series to be an ideal solution.
