描述 Description

The SP706R/S/T and SP708R/S/T series is a family of microprocessor (μP) supervisory circuits that integrate the myriad components required by discrete solutions which monitor power-supplies and batteries in μP and digital systems.
The SP706R/S/T and SP708R/S/T series significantly improve system reliability and operational efficiency when compared to solutions using 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.
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 required.
