Mp3378e Protection Pin Upd Direct

: These pins monitor individual LED strings for open or shorted conditions. If a string is damaged, the controller can disable that specific channel or the entire driver to prevent thermal runaway.

The MP3378E uses a resistor divider from VOUT (boost output) to the PROT pin. If the divider is incorrectly calculated or damaged: mp3378e protection pin upd

The MP3378E includes several built-in safety mechanisms for both the WLED controller and the buck converter: Protection Type Mechanism / Details : These pins monitor individual LED strings for

The MP3378E is a step-up (boost) controller IC designed for large-size LCD panel backlighting (TVs, monitors). Unlike typical boost controllers, it features a multi-function that serves as both an Over-Voltage Protection (OVP) input and a Start-Up timing capacitor node. If the divider is incorrectly calculated or damaged:

Not a separate pin – UPD refers to the via register or external logic on MP3378E (depending on variant). In practice:
