DESCRIPTION

The SP690T/S/R, SP802T/S/R, SP804T/S/R and SP805T/S/R devices are a family of

microprocessor (µP) supervisory circuits that integrate 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 SP690T/S/R, SP802T/S/R,

SP804T/S/R and SP805T/S/R devices include a watchdog timer, a µP reset and backup-

battery switchover, and power-failure warning; a complete µP monitoring and watchdog

solution. The series is ideal for 3.0V or 3.3V applications in portable electronics, computers,

controllers, and intelligent instruments and is a solid match for designs where it is critical to

monitor the power supply to the µP and it’s related digital components. Refer to Sipex's

SP690A/692A/802L/802M/805L/805M series for similar devices designed for +5V systems.
