    Good day all.

    I am looking for some help with identifying an smd part.

    The smd part is in a 6pin package and has the part number G4EE on it.

    This circuit board is the BMS board from an e-bike, the problem is that one of the cells under/over voltage protection does not seem to be working, and I feel that this part might be the issue so I am trying to find out what it is, and if possible to find a datasheet and or a suitable replacement part.

    Thanks for your time.

    Best Regards.

    First of all, what is the "BMS board"?

    As you may already know, a simple Google does not work... I could not find the G4EE code in on-line indexes.

    You may have to reverse engineer the circuit around the part to get a feel for what it is. For example, it could be a transistor, voltage comparator or an IC specially designed for this battery charging/sensing use. It is hard to tell looking at your (excellent) photo.

    I think that it is a microcontroller probably something like tinyAVR.
