X4003 Overview
These devices bine three popular functions, Poweron Reset Control, Watchdog Timer, and Supply Voltage Supervision. This bination lowers system cost, reduces board space requirements, and increases reliability. Applying power to the device activates the power on reset circuit which holds RESET/RESET active for a period of time.
