Hello,
We have an issue with the BQ51050BYFPR, we can not charge the battery with this component, we made a previous prototype using the BQ51050BRHLT and it worked charging a battery of 130mAh and and also a battery of 180mAh (Attached files).
We are using as coil receiver the WR202010-18M8-ID (11uH)
This circuit is not working, it does not charge
This is prototype circuit, this circuit works (it can charge the battery 130mAh or 180mAh) and basically is the same circuit, only change the package of the BQ51050B and transistor Q2 is not installed.
Please, could you check schematics attached and battery information, and give us a clue about how to solve the issue?
Best regards,
Heiner
