BQ25703A: how to get the output current under OTG mode

Dear sir,

I found the IIN_DPM() only show the input current of VBUS side. How can I get the output current of VBUS under OTG mode?

Thanks

OTG mode has its own output voltage register and current register. Detail setting can be found in datasheet.

Dear Wang,
I do not found the VBUS current read back register. The OTGCurrent() is to set the current limit of out VBUS, not the readback register. The ADCIINCMPIN() can read the input current of VBUS.

Thanks

In OTG mode, you can set the VBUS current. But, no ADC for VBUS current read back.

Dear Wang,

Hope BQ25703 can add the function in later version.

Thanks
