www.ti.com ............................................................................................................................................................................................ SLUS917 – FEBRUARY 2009
Seven 8-bit registers are used to control and read the status of the TPS2459. Registers 3 and 4 control the 12-V
channel. Rregister 5 controls the 3-V channel. Register 6 contains eight general configuration bits. Read-only
registers 7, 8, and 9 report back system status to the I2C controller. All ten registers use the I2C protocol and
are organized as follows shown in Table 1.
