The SP703/704 devices are 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 SP703/704 devices include a manual reset input, a P reset and backup-battery switchover, and powerfailure warning. The series is ideal for applications in computers, controllers, intelligent instruments and automotive systems. All designs where it is critical to monitor the power supply to the P and its related digital components will find the series to be an ideal solution. VBATT
