您好,过度放电导致STAT和PG端指示灯常亮,表示芯片Sleep mode或者 charge disable.
请将VBUS的电压恢复到正常范围看是否能恢复正常。
8.3.8.1 Power Good Indicator (PG)
The open drain PG pin goes low to indicate a good input source when:
1. VBUS above VVBUS_UVLO_RISING
2. VBUS below VVBUS_OV threshold
3. VBUS above VPOORSRC (typ. 3.7 V) when IPOORSRC (typ. 30 mA) current is applied (not a poor source)
4. Input Source Type Detection is completed
