BQ51013B: Yes

Part Number: BQ51013B
Other Parts Discussed in Thread: BQ24014

Greetings,

I am using BQ51013B in my design as a wireless charger. The issue that I have that unit starts charging then immediately stops.

Please see following a copy of my schematic,

One issue that I see immediately might be that I connect the Thermister pin of the battery to both BQ51013B and BQ24014. I probably need to connect the TS/CTRL of the BQ51013B to 10K and Ground. I am not sure if this would solve my problem.

Thanks,

ALi.

HI Ali

The schematic looks pretty good.

Coil is very good, this is a large coil that should work well.

The TS pin connection that you pointed out could be the main problem, for BQ51013B connect TS to ground with a 10k resistor to disable.

On other thing that may help is to swap R3 (66) and R6 (196), this will not change the ILIM value but increase the FOD margin and prevent it from causing problems.
