SERIAL INTERFACE
The serial interface is compatible with the standard and fast mode I
2
C specifications, allowing transfers up to
400 kHz. The interface adds flexibility to the power supply solution, enabling most functions to be programmed to
new values depending on the instantaneous application requirements and charger status to be monitored.
Register contents remain intact as long as V
CC
remains above 2 V. The TPS65013 has a 7-bit address with the
LSB set by the IFLSB pin; this allows the connection of two devices with the same address to the same bus. The
6 MSBs are 100100. Attempting to read data from register addresses not listed in this section results in FFh
being read out.

SLVS517–AUGUST 2004
For normal data transfer, DATA is allowed to change only when CLK is low. Changes when CLK is high are
reserved for indicating the start and stop conditions. During data transfer, the data line must remain stable
whenever the clock line is high. There is one clock pulse per bit of data. Each data transfer is initiated with a start
condition and terminated with a stop condition. When addressed, the TPS65013 device generates an
acknowledge bit after the reception of each byte. The master device (microprocessor) must generate an extra
clock pulse that is associated with the acknowledge bit. The TPS65013 device must pull down the DATA line
during the acknowledge clock pulse so that the DATA line is a stable low during the high period of the
acknowledge clock pulse. The DATA line is a stable low during the high period of the acknowledge-related clock
pulse. Setup and hold times must be taken into account. During read operations, a master must signal the end of
data to the slave by not generating an acknowledge bit on the last byte that was clocked out of the slave. In this
case, the slave TPS65013 device must leave the data line high to enable the master to generate the stop
condition.
The I
2
C interface accepts data as soon as the voltage at V
CC
is higher than the undervoltage lockout threshold
and one power rail of the converter (main, core, or one of the LDOs) is operating. Therefore, the I
2
C interface is
not operating after applying the battery voltage as the device automatically enters the WAIT mode with all rails
off.
When the device is in WAIT mode, the I
2
C registers are reset to their default values if all voltage rails are off. If
the device is in WAIT mode and one power rail is left on, the I
2
C interface is operating and the registers are not
reset after leaving the WAIT mode.
