DESCRIPTION

The SP703/704 devices are 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 SP703/704

devices include a manual reset input, a µP 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 µP and its related digital components will find the series to be an ideal solution.
