Figure 21. Typical parallel IGBT gate drive circuits with DESAT detection

The ACPL-336J has non-inverting gate control inputs, and an open drain FAULT and UVLO outputs suitable for wired

‘OR’ applications. The two supplies bypass capacitors (1 µF) provide the large transient currents necessary during a

switching transition. The DESAT diode and 220 pF blanking capacitor are the necessary external components for the

fault detection circuitry. The gate resistor (RG) serves to limit gate charge current and indirectly control the IGBT collector

voltage rise and fall times. The open drain FAULT and UVLO outputs have passive 10kΩ pull-up resistors and a 330 pF

filtering capacitor.
