Hi, Could you please confirmed if the I2C bus (SCL and SDA ) for TI chip BQ24192 and BQ27501 can be on 3.3V rail. In our design host side I2C bus voltage level is 3.3V. can we directly connect it to I2C bus signal of BQ24192 and BQ27501 through pull up to 3.3V rail or we need to use level shifter for I2C bus to convert the 3.3V rail to 1.8V for BQ24192 and BQ27501.

 

Thanks,

Bhupendar
