SPV1050 behavior after UVP threshold

Hello,

I would like to know what supposed to happen after the UVP threshold.

During my test, I put a load at the LDO2 output and after the UVP threshold (Vbatt at 3.7V) I removed the load. After that, I put a solar pannel on Vin. I don't know why but the Vstore and Vbatt voltage slowly decreased even though a Vin voltage was here. I noticed that the /BATT_CONN pin was high.

Is that a normal behavior of the SPV1050 ?

Thanks,

Please forgive me for my english.

Malo
