Figure 18. Serial I/F READ From TPS60251: Protocol B
Figure 19. Serial I/F Timing Diagram
The I2C interface uses a combined protocol in which the START condition and the Slave Address are both
repeated. The TPS60251 provides 2 I2C Slave Address using internal EEPROM in case more than 1 device is
used in the system. The primary I2C Slave Address is 1110111. For the alternative I2C address, contact the
factory.
