2ED2106S06F drive board for BLDC motor

Circuit diagram of the EVAL-M1-2ED2106S 

The worst-case test of the short circuit was done by linking the high-side IGBT collector and emitter in advance 

of the system run. The short circuit would be triggered once the low-side IGBT turns on. In the bench test, the 

total SCP delay time of the board was around 2.5 uS (see Figure 12), which meets the IGBT short-circuit 

capability.
