3.0V/3.3V Low Power Microprocessor Supervisory

Circuits

April 2015

Rev. 3.0.0

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.
