TPS6105X I2C UPDATE SEQUENCE
The TPS6105x requires a start condition, a valid I
2
C address, a register address byte, and a data byte for a
single update. After the receipt of each byte, TPS6105x device acknowledges by pulling the SDA line low during
the high period of a single clock pulse. A valid I
2
C address selects the TPS6105x. TPS6105x performs an
update on the rising edge of the SCL clock that follows the ACK bit transmission.

Following the successful acknowledgement of the slave address, the bus master will send a byte to the
TPS6105x, which will contain the address of the register to be accessed. The TPS6105x contains four 8-bit
registers accessible via a bidirectional I2C-bus interface. All internal registers have read and write access.
