| PRO state | Protection response | |-----------|----------------------| | LOW (GND) | – after fault (OVP, OCP, SCP, UVLO), driver shuts down and stays off until VCC cycled | | HIGH (>2V) | Auto-restart mode – after fault, driver tries to restart periodically (hiccup) |
The MP3378E doesn't have a single "protection pin." Instead, it uses a network of monitoring pins to trigger a shutdown if any safety threshold is exceeded. Understanding these pins is the key to diagnosing a backlight that flashes then dies. MP3378E - Monolithic Power Systems mp3378e protection pin upd
