Mp3378e Protection Pin Upd May 2026

Automatically shuts down the chip if internal temperatures reach unsafe levels.

Technicians sometimes attempt to "bypass" or "enable" protection pins to diagnose whether a failure is due to a faulty LED or the driver IC itself. mp3378e protection pin upd

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.

Technicians often check the resistor values for the OVP resistor divider to ensure the chip is receiving the correct feedback voltage. Troubleshooting and "Bypassing"
