output voltage/operation mode is updated at the same
time the IC sends the acknowledge for the I 2 C data
byte (see Figure 13).
Slave Address
A bus master initiates communication with a slave
device (MAX8952) by issuing a START condition fol-
lowed by the slave address. The slave address byte
consists of 7 address bits (1100 000x) and a read/write
bit (R/ W ). After receiving the proper address, the IC
issues an acknowledge by pulling SDA low during the
ninth clock cycle.
Other slave addresses can be assigned. Contact the
factory for details.
Write Operations
The IC recognizes the write byte protocol as defined in
the SMBus? specification and shown in Figures 14a and
14b. The write byte protocol allows the I 2 C master device
to send 1 byte of data to the slave device. The write byte
protocol requires a register pointer address for the sub-
sequent write. The IC acknowledges any register pointer
even though only a subset of those registers actually
7) The slave acknowledges the data byte.
8) The slave updates with the new data.
9) The master sends a STOP condition.
In addition to the write-byte protocol, the IC can write to
multiple registers as shown in Figure 14b. This protocol
allows the I 2 C master device to address the slave only
once and then send data to a sequential block of regis-
ters starting at the specified register pointer.
Use the following procedure to write to a sequential
block of registers:
1) The master sends a START command.
2) The master sends the 7-bit slave address followed
by a write bit.
3) The addressed slave asserts an acknowledge by
pulling SDA low.
4) The master sends the 8-bit register pointer of the
first register to write.
5) The slave acknowledges the register pointer.
6) The master sends a data byte.

The slave acknowledges the data byte.
The slave updates with the new data.
Steps 6 to 8 are repeated for as many registers in

3) The addressed slave asserts an acknowledge by
pulling SDA low.

incremented each time.
10) The master sends a STOP condition.
Read Operations
The method for reading a single register (byte) is
shown in Figure 15a. To read a single register:
