BQ51222: I2C speed specification

Part Number: BQ51222

Hi Champs,

The datasheet of BQ51222 says I2C speed is typical 100kHz. That does not prevent me from going higher so do you have any concerns using it in fast mode (400kHz)?

Best regards,

Simon Jagla

  • We are Checking but do not think 400kHz is possible with this device.

    Hi Bill,

    do you already have some results?

    I have found no info on testing at a speed faster that 100kHz, this is what I would recommend.
