X5001 Overview
This device bines three popular functions, Poweron Reset, Watchdog Timer, and Supply Voltage Supervision in one package. This bination lowers system cost, reduces board space requirements, and increases reliability. The watchdog timer provides an independent protection mechanism for microcontrollers.
