SP690SEN Product Details


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 backupbattery 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.
