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. 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 demanded.
