Part Number: BQ34110

Hi Team,

What's the purpose of LEN pin?

Can it be unused? If so, how to deal with it? 

Thanks and Best Regards!

    Hi Hao,

    LEN is an optional GPIO that can be used to directly control the external FET implementing the Learn Discharge Phase, or whether the host will control the external FET. The ways it can be configured are described in the TRM and EVM user guide.

    Best regards,
