Design Notes
Place decoupling capacitors (0.1 uF and 10 uF) close to VDD1 and VDD2 pins to ensure stable supply voltages. Use a low-ESR ceramic capacitor for high-frequency noise bypass. The input and output grounds (GND1 and GND2) should be kept separate to maintain isolation integrity.
Minimize the loop area of the gate drive circuit (VOUT to IGBT gate and return) to reduce parasitic inductance and ringing. Keep the DESAT sense trace short and route it away from high dv/dt nodes to avoid false triggering. Use a ground plane on the output side to reduce EMI.
Ensure the DESAT pin is properly connected to the IGBT collector through a high-voltage diode and resistor network. If DESAT is not used, tie it to VDD2 through a resistor to prevent false triggering. Also, verify that the input signal (VIN) is within the specified logic levels and that the enable pin (EN) is properly driven to avoid unintended shutdown.
