The MAXIM max6875 is a EEPROM-programmable power-supply sequencer/supervisor. The Maxim MAX6875 is an EEPROM-programmable power-supply sequencer/supervisor.
It provides timed outputs that can be used as a watchdog, if properly wired. It provides timed outputs that can be used as a watchdog, if properly wired.
It also provides 512 bytes of user EEPROM. It also provides 512 bytes of user EEPROM.
At reset, the max6875 reads the configuration eeprom into its configuration At reset, the MAX6875 reads the configuration EEPROM into its configuration

The Maxim MAX6874 is a similar, mostly compatible device, with more intputs
and outputs:
vin gpi vout
MAX6874 6 4 8
MAX6875 4 3 5
MAX6874 chips can have four different addresses (as opposed to only two for
the MAX6875). The additional addresses (0x54 and 0x56) are not probed by
this driver by default, but the probe module parameter can be used if
needed.
