In our design we plan on shutting off I2C pullups rail to keep leakage down to other chips on the board. Can bq25180 handle I2C lines floating/not pulled up while it itself is powered?
Would it cause any unexpected behavior?

Hi Igor,
When I2C lines are left floating, the device performs as expected. If no registers are changed, you will see default device behavior (10 mA charge, 4.6 SYS regulation, 160s watchdog, etc).
