Mp3378e Protection Pin Upd [best] -

The IC monitors the OVP pin voltage against an internal reference. To prevent the chip from sensing an over-voltage state when an LED string is weak or disconnected:

Locate the resistor divider network running from the boosted VLED rail to the .

If one string is significantly brighter or dimmer, the mp3378e protection pin upd

The MP3378E regulates a maximum of 350mA per string across four channels. The VLED pins continuously read channel feedback:

+-----------------------+ | MP3378E | | TSSOP-28 | | | ------> OVP (Over-Voltage) | ------> COMP (Compensation) | ------> ISET (Current Set) | ------> EN1 (WLED Enable) | ------> EN2 (Buck Enable) | | | +-----------------------+ OVP (Over-Voltage Protection) Pin The IC monitors the OVP pin voltage against

The is a 4-channel WLED controller and high-efficiency buck converter primarily used for LCD backlight applications. While it does not feature a single pin explicitly labeled "Protection," its safety functions are distributed across several dedicated pins: Key Protection Pins and Functions

: Detects severe faults in the power path (e.g., a shorted boost diode) and immediately halts operation. typical)

Used in battery-powered systems where deep discharge operation is needed, but output regulation may suffer.

typical). This is often a , meaning the IC restarts once it cools.
