BQ25895's D+, D- multiplexing.

You can float D+/D-, resulting in unknown adapter and ILIM = 500mA or short them together, resulting in USB DCP and ILIM = lower of ILIM resistor or 3.25A.

I don't wanna float it neither short it. because I still wanna use BQ's handshake for MAXCharger , But I wanna still be using the d+,d- for output fast charging handshake ic..

Should I analog switch ic that can switch for bq d+,d- for charing input, and other handshake ic for output ?

What I wanna do is just wire both d+, d- bq and other output handshake ic and I send i2c command to bq to make it float , so i can use it for output ic.

is that possbible?

Yes, you can use an multiplexing switch to disconnect the charger's D+/D-. They are only used to set input current limit or do handshake to change the voltage on HVDCP adapters.
