Hi

 

I have product with LPC1837JBD144. I sold 3k+ of products to the market.

We get warranty claim from our customers, and we found LPC1837 MCU has short circuit VDD to GND. We have 5 this type of accidents and we need to understand how the LPC1837 fail.

One of faulty LPC1837JBD144 had short circuit, after we applied 3.3V to vdd with higher current it started to work again.

Does anyone had similar problems?
