X45620 Overview
The Intersil X45620 bines power-on reset control, battery switch circuit, watchdog timer, supply voltage supervision, secondary voltage supervision, block lock protect and serial EEPROM in one package. 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 active for a period of time.
