SP705-SP708-SP813L

Low Power Microprocessor Supervisory Circuits

June 2010

Rev. 2.0.0

GENERAL DESCRIPTION

APPLICATIONS

The SP705-708/813L series is a family of

microprocessor (µP) supervisory circuits that

integrate myriad components involved in

discrete solutions which monitor power-supply

and battery in mP and digital systems.

• Processors & DSPs Based Systems

• Industrial & Medical Instruments

FEATURES

The SP705-708/813L series will significantly

improve system reliability and operational

efficiency when compared to solutions

obtained with discrete components. The

features of the SP705-708/813L series include

a watchdog timer, a µP reset, a Power Fail

Comparator, and a manual-reset input.

• Precision Voltage Monitor

− SP705/SP707/SP813L: 4.65V

− SP706/SP708: 4.40V

• 200ms RESET Pulse Width

• Independent Watchdog Timer

− 1.6s Timeout (SP705/SP706/SP813L)

The SP705-708/813L series is ideal for

• 60µA Maximum Supply Current

applications

computers,

automotive

and

systems,

intelligent

controllers,

• Debounced TTL/CMOS Manual Reset

instruments. The SP705-708/813L series is an

ideal solution for systems in which critical

monitoring of the power supply to the µP and

related digital components is demanded.

Input

• RESET Asserted Down to V_CC=1.1V

• Voltage Monitor for Power Failure or

Low Battery Warning

• 8-Pin PDIP, NSOIC and MSOP Packages

• Pin Compatible with Industry

Standards 705-708-813L Series

• Functionally Compatible to Industry

Standard 1232 Series
