10.2.2.7 DESAT Pin Protection
Switching inductive loads causes large, instantaneous forward-voltage transients across the freewheeling diodes of the IGBTs. These transients result in large negative-voltage spikes on the DESAT pin which draw substantial current out of the device. To limit this current below damaging levels, a 100-? to 1-k? resistor is connected in series with the DESAT diode.
Further protection is possible through an optional Schottky diode, whose low-forward voltage assures clamping of the DESAT input to GND2 potential at low-voltage levels.
