If the fifth resistor R5 is not provided, when an overcurrent fault occurs, a collector current Ic is particularly large to trigger DESAT overcurrent protection, and the large Ic has great damage to the power device 200; since C ═ i × dt/dU can be obtained from i ═ C × dU/dt (i is a current value, C is a capacitance value, U is a voltage value, and d is a differential operator), the voltage change Δ U to reach the overcurrent protection threshold value can be reduced by a voltage drop in the fifth resistor R5, and the first capacitor C1 with a larger capacitance value can be selected, and the larger the capacitance value, the stronger the immunity to interference.

It can be understood that the sixth capacitor C6 and the fifth capacitor C5 not only filter the power of the high voltage part, but also improve the load capacity of the high voltage part.
In addition, the driving chip 11 further includes a VEEA pin, wherein the VEEA pin is connected to the second power supply pin VEE 2.
