X40011 - Xicor

X40011 Dual Voltage Monitor with Integrated CPU Supervisor

The X40010/11/14/15 combines power-on reset control, watchdog timer, supply voltage supervision, and secondary voltage supervision, in one package. This combination 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. .
