My evaluation module completely stopped working. Upon visual examination, I see U2 and U3 both have pin-head sized holes burned right through their plastic casings. I need to figure out why or how this happened. Is it an isolated incident or is this a known issue with the transmitter design?
I have designed a new product that uses Qi charging and my biggest concern is if my product has caused the evaluation module to fail. I suspect that is not possible because the evaluation module ought to control itself well enough to not fry it's own ICs. I am using a 3A power supply per specification.
Please help me diagnose the cause of failure for my TI evaluation module!
