2ED2106S06F drive board for BLDC motor

Circuit diagram of the EVAL-M1-2ED2106S 

7.2

Main power circuit

The gate drivers and IGBTs is designed as Figure 9. Each PWM signal to the gate driver’s input involves a resistor 

in series to suppress the noise induced from the ground bouncing while the IGBT switching. The ON and OFF 
gate resistors are separated for an optimized tradeoff between the IGBT switching loss and system EMI 

performance. 

The DC bus status is sampled by a resistor divider. 

Figure 9

Main power circuit 

7.3

 OCP circuit

The overcurrent protection (OCP) function is necessary for motor drive applications. As configured in Figure 10, 

the output of the comparator LM393A shall flip-flop low when the single-shunt current is over 5.45 A. The 

generated gate kill (GK) signal is sent to the controller IC disabling all the gate driver PWM inputs to turn off the 

IGBTs.
