Product Summary
The SP705EN-L is a microprocessor (mP) supervisory circuit that integrates myriad components involved in discrete solutions which monitor power-supply and battery in mP and digital systems. The SP705EN-L will significantly improve system reliability and operational efficiency when compared to solutions obtained with discrete components. The features of the SP705EN-L series include a watchdog timer, a mP reset, a Power Fail Comparator, and a manual-reset input.
