Mp3378e Protection Pin Upd |work| [TESTED]
Current sinks for the 4 LED strings; failures here often trigger protection.
The MP3378E is housed in a 28-pin TSSOP package with an exposed pad for heat dissipation. Primary Function mp3378e protection pin upd
While specific to other ICs like the ACM20005, common technician tricks involve using a diode or resistor to ground a protection pin to see if the backlight stays on. Warning: Bypassing protection on the MP3378E can lead to permanent damage to the IC or the LED panel if the underlying fault (like a short circuit) is not fixed.
