SP703/SP704
Low Power Microprocessor Supervisory
with Battery Switch-Over
The
SP703/704
devices
are microprocessor (
μ
P) supervisory circuits that integrate a myriad
of components involved in discrete solutions to monitor power-supply and battery-control
functions in
μ
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
μ
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
μ
P and its related digital components will find the series to be an ideal solution.
