X40011 Overview
The X40010/11/14/15 bines power-on reset control, watchdog timer, supply voltage supervision, and secondary voltage supervision, in one package. This bination lowers system cost, reduces board space requirements, and increases reliability. Applying voltage to VCC activates the power on reset circuit which holds RESET/RESET active for a period of time.
