Product Summary
The SP708CP is a microprocessor (μP) supervisory circuit that integrates myriad components involved in discrete solutions which monitor power-supply and battery in μP and digital systems. The SP708CP will significantly improve system reliability and operational efficiency when compared to solutions obtained with discrete components. The features of the SP708CP include a watchdog timer, aμP reset, a Power Fail Comparator, and a manual-reset input. The SP708CP is ideal for applications in automotive systems, computers, controllers, and intelligent instruments. The SP708CP is an ideal solution for systems in which critical monitoring of the power supply to the μP and related digital components is demanded.
