BQ25703A: CHRG_OK toggles in OTG mode

Part Number: BQ25703A

Hi,

if I pull the plug off my power supply and enable OTG, the CHRG_OK pin goes high every second or so and the AC_STAT bit also toggles.

The OTG_ON_CHRGOK bit is not set!

For my understanding this should not happen?

How can I detect the correct plug-in now?
