I wants to use ADUM5230 with AUIRGB4062D1 in new device (AC 3-phase motor converter, 100...350V in dc power line). Max switching frequency: 20 kHz. Gate capacitance: about 1,5 nF Questions: 1. Can I use ADUM5230 with AUIRGB4062D1 without output buffer transistors with good reliability? 2. What internal circuit is in ADUM5230 outputs A and B. What output resistance have outputs A and B? 3. There are parameters "output short-circuit pulsed current" "sourcing" and "sinking" in datasheet on ADUM5230. (100/300 mA, "short-circuit duration is less than 1 sec") What difference between "...sourcing" and "...sinking"? Can I do output current 2 A with time 1 us with frequency 12 kHz whithout damage from A and B outputs? What voltage loss between internal dc/dc-converter output and output A when output current 2 A (1 us current pulse from 10 uF external capacitor betwean Viso and GNDiso)? Also what voltage loss betwean Vddb and output B when output current 2 A (1 us current pulse).
