Part Number: BQ24190
Hello
The BQ24190 should normally detect weather the charger is an AC plug (USB_D+ connected to USB_D- inside the charger) or a laptop.
Unfortunately this detection doesn't work.
In our case, charger is seen as "unknown". Register 0x08 has value 0x24.
If I plug a laptop, detection is OK. Register 0x08 has value 0x6C.
USB communication works fine, because the same USB is used by our CPU.
Attached is our schematic. We have 2 battery chargers for the same battery (either from USB connector "rear" or USB connector "front")
Any idea, known issue ?
In case of "unknown" charger, what be be the charging current ?
Regards
Michel
