SP706REN-L/TR

监控电路 3.0V/3.3V Low Power Microprocessor Supervisory Circuits

GENERAL DESCRIPTION  SP706REN-L/TR

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.
