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.
