Key Differentiators
- Higher peak output current than ADUM4135BRWZ (vs ADUM4135BRWZ)
- Desaturation protection not available on UCC21520DW (vs UCC21520DW)
- Higher secondary supply voltage than UCC21520DW (vs UCC21520DW)
Design Notes
Ensure adequate decoupling on both VDD1 and VDD2 supplies. Place a 0.1 uF ceramic capacitor as close as possible to each supply pin, and a 10 uF electrolytic capacitor for bulk energy storage. The secondary supply should be able to provide the peak gate charge current without significant voltage droop.
Minimize the loop area between the gate driver output and the IGBT gate-emitter to reduce parasitic inductance. Use a dedicated ground plane for the secondary side and keep the DESAT sense trace short and shielded to avoid false triggering. Follow the layout guidelines in the ADuM4136 datasheet for optimal performance.
Do not exceed the absolute maximum ratings for VDD2 (35 V) and ensure the DESAT blanking time is set correctly to avoid false desaturation detection during normal switching. The Miller clamp should be connected to the IGBT gate to prevent dv/dt-induced turn-on. Verify that the input signal levels are compatible with the primary side logic thresholds.
