Figure 19. Serial I/F Timing Diagram
The I
2
C interface uses a combined protocol in which the START condition and the Slave Address are both
repeated. The TPS60250 provides two I
2
C Slave Addresses using an internal EEPROM in case more than 1
device is used in the system. The TPS60250 primary I
2
C Slave Address is 1110111 and the TPS60252 primary
I
2
C Slave Address is 1110110. For the alternative I
2
C addresses, contact the factory.
