GENERAL 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 mP 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.
