X40430 Datasheet (Xicor) - Triple Voltage Monitor

X40430, Triple Voltage Monitor

The X40430/31 combines power-on reset control, watchdog timer, supply voltage supervision, secondary and third voltage supervision, manual reset, and Block Lock™ protect serial EEPROM in one package.

This combination lowers system cost, reduces board space requirements, and increases reliability.
