Hi team,

My TSR colleague posted question and 1 week past with no reply.

Could you please reply below thread ASAP?

Please answer for if applying I2C signal from MCU w/o powering BQ27520 is okay or not.

Hi,

The datasheet states the Abs. Max. voltage for these pins is 5.5V, so it should not damage the device.

Best regards,

Matt
