MOT Protection Mode
The MOT protection prevents reverse current in SR MOSFET which could happen at light load if the MOT
time is set very long. The IC disables the gate output in the protection mode and automatically resume to
normal operation as the load increasing to a level where the SR current conduction time is longer than MOT.
This function works in both flyback and resonant half-bridge topologies. Figure 9 is an example in Flyback
converter.
