您好，请参考下面的内容
The BQ24780S operates only as a slave device with the address 0x12H. There are 3 options to avoid a potential SMBus address conflict between the two BQ24780S chargers:
Have two separate SMBus communication buses to control each BQ24780S charger independently. You mentioned that the EC has two sets of SMBus communication lines, so this solution should work for the customer's application.
Use an SMBus mux
Use the BQ25713 and the BQ25713B. These two chargers are identical, but they have different I2C addresses for more convenient dual charger operation.
