706P/R/S/T
and
708R/S/T
The SP706P/S/R/T, 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 SP706P/S/R/T, SP708R/S/T series will significantly
improve system reliability and operational efficiency when compared to results obtained with
discrete components. The features of the SP706P/S/R/T, SP708R/S/T series include a
watchdog timer, a
µP
reset, a Power Fail Comparator, and a manual-reset input. The SP706P/
S/R/T, SP708R/S/T series is ideal for +3.0V or +3.3V applications in automotive systems,
computers, controllers, and intelligent instruments. The SP706P/S/R/T, 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.
