DESCRIPTION
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 power-
failure 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.
