Pin Upd New!: Mp3378e Protection

Monitors the current through the external switching MOSFET and LED strings to prevent damage from excessive power draw.

: Leveraging the buck converter's OCP to ensure that even if the backlight fails, the internal standby power remains stable for diagnostic reporting to the main system processor. MPS | Monolithic Power Systems

The buck converter integrates its own protection mechanisms. mp3378e protection pin upd

For detailed design-in support, refer to the official MP3378E datasheet and EV3378E-F-00A evaluation board documentation available from MPS.

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. Pinout Summary (TSSOP-28 EP Package) Monitors the current through the external switching MOSFET

Common external circuits:

Check the voltage at the OVP pin (resistor divider from Boost output to Ground). 3. Check for False Triggers For detailed design-in support, refer to the official

If your monitor backlight flashes and immediately turns off (or doesn't turn on at all), the MP3378E is likely entering protection mode. 1. Identify the Faulted Pin/String
