Product Summary

The SP706TCU-L/TR is a microprocessor (μP) supervisory circuit that integrate myriad components involved in discrete solutions which monitor power-supply and battery, in μP, and digital systems. The SP706TCU-L/TR will significantly improve system reliability and operational efficiency when compared to results obtained with discrete components. The features of the SP706TCU-L/TR include a watchdog timer, a μP reset, a Power Fail Comparator, and a manual-reset input. The SP706TCU-L/TR is ideal for +3.0V or +3.3V applications in automotive systems, computers, controllers, and intelligent instruments. The SP706TCU-L/TR is an ideal solution for systems in which critical monitoring of the power supply to the μP and related digital components is demanded.
