Hello TI experts,
My customer tests BQ24616 in their own PCB, and they found one problem.
Here is some conditions of fault situation.
1. they attached battery to a charger first, and apply VIN (DC adapter, 12V)
2. and they could see VIN and BAT voltage on SYSTEM power repetitively.
3. they tested 100 pcs of charger and saw it 5. and it could be more because it appears ramdomly.
4. They can see it for all batteries (not particular battery), especially the battery with 98% or more capacity.
I attach a schematic and the waveform of each point. You can see it at point 1.
I think that V_OUT should be same with VIN when VIN is present. could you check why does it happen?
Please check this issue. Thanks.
Best regards,
Chase
