GENERAL DESCRIPTION
The SP706R/S/T and SP708R/S/T 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 SP706R/S/T and SP708R/S/T series will
significantly improve system reliability and
operational efficiency when compared to
solutions obtained with discrete components.
The features of the SP706R/S/T and
SP708R/S/T series include a watchdog timer, a
μP reset, a Power Fail Comparator, and a
manual-reset input.
The SP706R/S/T and SP708R/S/T series is
ideal for 3.0V or 3.3V applications in
automotive systems, computers, controllers,
and intelligent instruments. The SP706R/S/T
and SP708R/S/T series is an ideal solution for
systems in which critical monitoring of the
power supply to the μP and related digital
components is demanded.
