您好，电路上看您的D+,D-没有接。
if D+/D- is left floating, input current limit is determined by the resistor value at ILIM pin and charge current is set by the resistor value at ICHG pin. The actual charge current is determined by both ILIM and ICHG depending which one allows lower charge current. The charge current cannot reach the set value. As I mentioned earlier, this could be caused by the battery impedance. Please measure the voltage at BAT pin, if BAT pin voltage has reached the charge voltage, then the charge current is determined by battery terminal voltage and impedance (CV mode).
