Design Notes
For optimal performance, place the ADUM4137BRWZ-RL7 close to the IGBT gate to minimize gate loop inductance. Use separate ground planes for the input and output sides, and connect them only at the isolation barrier. Ensure the DESAT pin is connected to the IGBT collector through a high-voltage diode and a resistor to set the blanking time. The Miller clamp pin should be connected to the gate with a low-inductance trace to effectively suppress false turn-on.
The secondary supply (VDD2) should be decoupled with a 10µF ceramic capacitor and a 0.1µF capacitor placed close to the VDD2 and GND2 pins. The input supply (VDD1) should also be decoupled with a 1µF capacitor. Ensure the supply voltages are within the recommended operating range to avoid damage. The DESAT blanking capacitor should be selected to provide adequate blanking time without delaying fault detection.
The ADUM4137BRWZ-RL7 dissipates power internally, especially at high switching frequencies. Ensure adequate PCB copper area for heat dissipation, particularly under the package. The thermal resistance of the 28-SOIC-W-FP package is moderate, so for high-power applications, consider adding thermal vias to a ground plane. Monitor the junction temperature to stay within the absolute maximum ratings.
