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,  
in  
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.
