Mp3378e Protection Pin Upd //free\\ <2026>

Sets the LED current; a resistor between this pin and ground programs the brightness.

Current sinks for the 4 LED strings; failures here often trigger protection.

Enables the IC and controls brightness via pulse-width modulation. mp3378e protection pin upd

Over-Voltage Protection input; senses output voltage via a resistor divider. Sets the LED current; a resistor between this

Open-string protection is achieved by monitoring the voltage on the OVP pin. If an LED string fails, the controller may boost output voltage excessively; if it hits the programmed OVP threshold, the chip shuts down to prevent damage.

The MP3378E is housed in a 28-pin TSSOP package with an exposed pad for heat dissipation. Primary Function 26 May 2017 — * MP3378E

Limits current to the external MOSFET and internal buck converter.
