I am considering the bq4050 for a 2S design that only needs LED outputs so no I2C communications or high accuracy will be needed. Since this gauge is CEDV, does that mean that each production pack will need a qualified LEARN cycle? Or will simply loading a golden file and calibrating each pack be sufficient?
If such a pack would require a LEARN cycle and we wish to avoid it, what would be the next best alternative (trying to keep the design as simple and low cost as possible)? I considered the bq34z100 or bq78z100 but would like to use an integrated protector so I can shut off the FETs when the battery is removed from the Host or charger using a Presence pin.
