... At the inception of an overvoltage event, all PWM outputs are commanded low instantly (less than 20ns) until the voltage at VDIFF falls below 0.4V. This causes the Intersil drivers to turn on the lower MOSFETs and pull the output voltage below a level that might cause damage to the load. The PWM outputs remain low until VDIFF falls below 0 ...
