Integrated desaturation logic provides all mode of overcurrent protection, including ground fault protection. The sensing desaturation input is provided by active bias stage to reject noise. Soft shutdown is predominantly initiated in the event of overcurrent followed by turnoff of all six outputs. A shutdown input is provided for a customized shutdown ...
