Hi, team,
My customer is testing bq24297, we found a strange phenomenon.
ICHG=1.5A (approximately), Iin_limit=3A, adaptor is 5V/1A, we found when we reduced Vin_DPM setting value, the input current also decreased, and the voltage at VBUS pin also decreased to the same value as set Vin_DPM. But in theory, lower Vin_DPM allows bigger input current, how come the voltage drop on the USB wire become bigger when the current become smaller?
