Part Number:BQ25606
The BQ25606 IC is connected to a micro-usb port. Both D+/D- lines are connected to the D+/D- ports on BQ25606 IC. The ICHG and ILIM current are both set to 1A. My goal is to charge the battery at 500mA when connected to SDP and at 1A for wall adapters. However, when measuring the charging current I am only seeing approx 420mA (max) its when connected to SDP and only 530mA (max) when connected to a wall adapter. Please advise on why the charging current is not reaching 1A when connected to wall adapters. Is there additional circuitry needed to connect the D+/D- lines to the IC?
Thank You,
