SP706R/S/T - SP708R/S/T

3.0V/3.3V Low Power Microprocessor Supervisory

Circuits

June 2010

Rev. 2.0.0

GENERAL DESCRIPTION

APPLICATIONS

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.

• Processors & DSPs Based Systems

• Industrial & Medical Instruments

FEATURES

• Precision Low Voltage Monitor

− SP706R/SP708R: +2.63V

− SP706S/SP708S: +2.93V

− SP706T/SP708T: +3.08V

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.

• 200ms RESET Pulse Width

− SP706R/S/T: Active Low

− SP708R/S/T: Active High and Active Low

• Independent Watchdog Timer

− 1.6s Timeout (SP706R/S/T)

− Enable/Disable Function

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.

• 40µA Maximum Supply Current

• Debounced TTL/CMOS Manual Reset

Input

• RESET Asserted Down to V_CC=1V

• V_CCGlitch Immunity

• Voltage Monitor for Power Failure or

Low Battery Warning

• 8-Pin NSOIC and MSOP Packages

• Pin Compatible with Industry

Standards 706R/S/T and 708R/S/T
