SP704 Datasheet | Sipex

DESCRIPTION The SP703/704 devices are microprocessor (µP) supervisory circuits that integrate a myriad of ponents 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 pared to discrete solutions. The features of the SP703/704 devices include a manual reset input, a µP reset and backup-battery switchover, and powerfailure warning. The series is ideal for applications in puters, controllers, intelligent instruments and automotive systems. All designs where it is critical to monitor the power supply to the µP and its related digital ponents will find the series to be an ideal solution.
