    Hi Went,

    No. The BQ77905 family does not provide overcurrent during charge protection. If you are looking for that feature, it is on the BQ77915. This is a very similar device. The only difference is the BQ77915 offers the OCC, cell balancing, and a HIBERNATE mode. Here is the datasheet:

    Description of the OCC function can be found in Section 9.3.2.8 of the datasheet. Here is where you can find details on the function and how to test it.
