SP706SEN-L/TR

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

GENERAL DESCRIPTION SP706SEN-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.
