BQ25756: Overcurrent error.

Part Number: BQ25756


Tool/software:

Hi,

The PG 、STAT1 LED is on ,the en PIN is low .charge state is trickle .When I connect the battery to the charger ,the STAT2 led is  on.and get an overcurrent error. I found th charge current(REG0x2F) rise up to -32532mA. Do I need to add a diode between the charger and the battery.

If the EN pin is high ,I connect the charger to the battery.The PG led start blinking.

 Please help me analyze the reasons! Thank you!

 Best regards,
