Power Device Status Register (Continued) 204/1204

Inverter Power Device Fault Bit 6

The Inverter Power Device Fault bit is set if

the gate driver turns off an output power

device (IGBT) to protect it from an

overcurrent.

Bit 3 in register 202 will also be set.

Hex Value: 0040H

UDC Error Code: N/A

LED: N/A

If an output short circuit occurs, a high current will flow in the IGBT causing its

collector-to-emitter voltage to increase to a level much higher than normal. The

gate driver detects this condition and instantly shuts off the IGBT to prevent its

destruction.
