The X40420/21 devices have a Power On Reset (POR)
circuit, low voltage monitors for two supplies, an automatic
switch between a main voltage source and a
backup supply, a watchdog timer, 4kbits of EEPROM and
a fault detection register. Some of these features are
re-settable, such as the POR time period, the watchdog
timer duration and block protection of the EEPROM. All
of these features make the X40420/21 very versitile
devices in a power supply management application.
