Hi,
When we connect PG pin to EN pin and sunlight is not enough, the IC doesn't stabilize. And 30uA current sinks from battery to IC.
To prevent this should i add another Schottky diode to BAT pin of the IC before CN2.
Best Regards.

Hello
Adding an diode between BAT pin and battery will create other problems, Battery Detect may trip and charge voltage will be low.
the IC doesn't stabilize
Can you describe the condition a little more?
Hi,
The condition is similar to this question below:
" When the output power of the solar panel is low in weak sunlight or natural light, use oscilloscope capture the EN pin waveform, the EN pin jumps high and low.
At this time, the battery goes to the chip through the BAT pin the internal sink current is 20-30μA. How to avoid this phenomenon? "
Best regards.
