DESCRIPTION…

The SP705-708/813L series is a family of microprocessor (µP) supervisory circuits that

integrate myriad components involved in discrete solutions which monitor power-supply and

battery in µP and digital systems. The SP705-708/813L series will significantly improve

system reliability and operational efficiency when compared to solutions obtained with discrete

components. The features of the SP705-708/813L series include a watchdog timer,

a µP reset, a Power Fail Comparator, and a manual-reset input. The SP705-708/813L

series is ideal for applications in automotive systems, computers, controllers, and intelligent

instruments. The SP705-708/813L series is an ideal solution for systems in which critical

monitoring of the power supply to the µP and related digital components is demanded.
