DESCRIPTION…
The SP705-708/813L/813M series is a family of microprocessor ( P) supervisory circuits that
integrate myriad components involved in discrete solutions which monitor power-supply and
battery in P and digital systems. The SP705-708/813L/813M series will significantly improve
system reliability and operational efficiency when compared to solutions obtained with discrete
components. The features of the SP705-708/813L/813M series include a watchdog timer,
a P reset, a Power Fail Comparator, and a manual-reset input. The SP705-708/813L/813M
series is ideal for applications in automotive systems, computers, controllers, and intelligent
instruments. The SP705-708/813L/813M series is an ideal solution for systems in which critical
monitoring of the power supply to the P and related digital components is demanded.
