8. Short−circuit current protection functions only at the low−sides because the sense current is divided from main current at low−side IGBTs.

Inserting the shunt resistor for monitoring the phase current at NU, NV, NW terminal, the trip level of the short−circuit current is changed.

9. The fault−out pulse width tFOD depends on the capacitance value of CFOD according to the following approximate equation :

tFOD = 0.8 × 106 × CFOD

10.TTH is the temperature of thermistor itself. To know case temperature (TC), conduct experiments considering the application.
