Hi Team,

May I know bq25890 D+/D- can implement as below? or just only can use mux to switch status.

    Hi Kuo,

    The D+/D- lines go high impedance following the first 2 seconds after power up. If your host can be programmed to not use the D+/D- until after the bq25890 status registers reports power is good, then you should not need a MUX.
