The MP3378E Datasheet details several pins dedicated to establishing and monitoring protection thresholds. Tweaking these specific inputs can alter or bypass the protection state.
Place a high-quality, low-ESR ceramic capacitor near the VCC1 pin to suppress gate driver switching noise. mp3378e protection pin upd
The MP3378E PROT pin is not a simple OVP input—it controls the entire start-up sequence. For a successful design (UPD): The MP3378E Datasheet details several pins dedicated to
The device includes recoverable thermal protection. If the junction temperature exceeds its safety threshold, the IC shuts down and resumes operation once it cools. The "Protection Pin" Logic (UPD) The MP3378E PROT pin is not a simple

: The voltage on this pin stays safely below its internal threshold (typically 1.23V).
