Problems we have actually had to solve.
Not product promotions. Each note takes one real design problem, shows what was measured, explains why it happens, and ends with the datasheet check that prevents it next time.
No notes match that. Try a different term.
Latch-up: the protection device that never turned off
The board passes every functional test. Then it goes through ESD testing, and one port stops working. The protection device is warm. Replace it, power-cycle, and the board is fine again, until the next discharge. The part is not too weak. It is still switched on.
Read the noteNegative-voltage EOS: the supply that went below its own ground
Units come back from the field with the touch controller destroyed. The obvious suspect is a discharge on the touch lines, so the argument becomes which protection device to fit. Then somebody scopes a returned unit while it is running, with nobody touching it, and finds -3.26 V on the 3.3 V rail.
