SP690T/S/R, SP802T/S/R,
SP804T/S/R, and SP805T/S/R
3.0V/3.3V Low Power Microprocessor
Supervisory with Battery Switch-Over
The SP690T/S/R, SP802T/S/R, SP804T/S/R and SP805T/S/R devices are a family of
microprocessor (
µ
P) supervisory circuits that integrate a myriad of components involved in
discrete solutions to monitor power-supply and battery-control functions in
µ
P 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
µ
P reset and backup-
battery switchover, and power-failure warning; a complete
µ
P 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
µ
P and it’s related digital components. Refer to Sipex's
SP690A/692A/802L/802M/805L/805M series for similar devices designed for +5V systems.
