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 P reset and backup- battery switchover, and power-failure warning a complete 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 P and its related digital components. Refer to Sipex s SP690A/692A/802L/802M/805L/805M series for similar devices designed for +5V systems.
