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.
