Mp3378e Protection Pin !!exclusive!! Direct

Monitors the inductor current for the WLED controller to provide Over-Current Protection (OCP) .

Some designers add an external 10kΩ pull-up to 3.3V to improve noise immunity. This prevents the IC from pulling the pin low because the external source fights the internal MOSFET. Result: The IC detects a fault, but the pin stays high, so the MCU never sees it. mp3378e protection pin

The PROT pin is sensitive to slow edges. Always use a clean logic signal to drive it. Monitors the inductor current for the WLED controller
