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.
