Key Differentiators
- Higher isolation voltage compared to ADUM3223ARWZ (vs ADUM3223ARWZ)
- Faster propagation delay compared to UCC21520DW (vs UCC21520DW)
- Same package and pinout as ADUM4223ARWZ (vs ADUM4223ARWZ)
Design Notes
Place decoupling capacitors (0.1 µF and 10 µF) close to the VDD1 and VDD2 pins to ensure stable supply voltages. Use a solid ground plane for GND1 and GND2 to minimize noise and parasitic inductance. Keep the high-side and low-side output traces short and wide to reduce inductance and improve switching performance.
The ADUM4220ARWZ can dissipate significant power when driving large gate capacitances at high frequencies. Ensure adequate PCB copper area for heat dissipation, especially in high-temperature environments. The SOIC-16 package has a thermal resistance of approximately 80°C/W; consider adding thermal vias if operating near maximum ratings.
Do not exceed the absolute maximum ratings for VDD1 and VDD2. Ensure the dead-time control input (DT) is properly configured to prevent shoot-through in half-bridge topologies. Verify that the input signals (VIA and VIB) are within the specified logic levels and have sufficient pulse widths to meet the minimum pulse width requirement.
