Hi team,

Can BQ25890 I2C connect with 3.3v through 10kohm? Our datasheet shows it connect to 1.8v. In my opinion, it can.

Thank you.

Hello Frank,

Yes, you can use a 3.3V and 10k pull-up for I2C on the 890.

The 1.8V pull-up rail on the I2C specifications on the datasheet means that the specs were defined when using a 1.8V rail, but a 3.3V rail can be used.
