sequence begins. All EEPROM bits are copied to the
EEPROM from the scratchpad with a single
SET_WRITE_EE command. This command also sets an
internal BUSY flag to mask all other incoming signals.
SET_WRITE_SCH: The SET_WRITE_SCH command
transfers data to the scratchpad. The 4 MSBs contain the
register address and the 4 LSBs contain the data to be
written. The internal BUSY flag is not set by this com-
mand. Table 11 shows the MAX16816 EEPROM memory
organization. Use the SET_WRITE_EE command to trans-
fer data from the scratchpad to the EEPROM.
programming purposes. Ensure that V CC is greater
than the UVLO threshold because both UVEN and
FAULT are pulled up to 5V. See the Electrical
Characteristic tables for details.

SET_READ_SCH: The SET_READ_SCH command is
the command to read data in the scratch pad buffer.
Once the MAX16816 receives the SET_READ_SCH
command, data on the scratchpad register is shifted

the SET_READ_SCH sequence. The BUSY signal is not
set by this command.

Programming
To program the MAX16816 on-chip EEPROM with a
pulldown device, directly connect FAULT to the DATA
IN input of a microcontroller (μC). Also, connect FAULT
to the DATA OUT output of a μC using an external
switch (Figure 5). Connect the EN of the μC directly to
