Dear TI Team.
My customer developed A6 Type charging pad using BQ500410A. However, 30 of 250 sets didn't work properly - No charge, LED display error, and so on...
I found the defect of INA199A1. The output of INA199A1 is 3.3V or 1.3V in spite of no RX on the TX Pad.
Assuming non-FOD, If I replace defected INA199A1 with new or pulled I_Sense down to GND, the all of defected PWB ass'y works well.
In normal, the output voltage of INA199A1 will increase as the current increases. Anyway, I want to know how I_Sense pin effects the behaviour of BQ500xxx.
I'll check the reason why INA199A1 was defected.
