BQ25895 sw pins strange waveform

Hi

Im measuring sw pins waveform

I pulled up sda scl but never sent any i2c command so it should be the same as standalone mode and OTG pin is pulled  down

Vbus is 12v

So im  expecting

Datasheets figure 55.

But its peak is  like 5V

So it loooks more like

Figure 57

And measured current is 300mA from vbus

Im confused

How could i force the ic put in charger mode only ? Let me know

Thank you!
