Key Differentiators
- Higher isolation voltage (5000 Vrms) compared to ADUM3223ARWZ (vs ADUM3223ARWZ)
- Automotive-grade variant available (vs ADUM4223WCRWZ)
- Fast propagation delay (38 ns) enables high-frequency operation (vs ADUM3223ARWZ)
Design Notes
Place decoupling capacitors (0.1uF and 10uF) close to VDD1 and VDD2 pins to ensure stable supply voltages. Use low-ESR ceramic capacitors and minimize trace lengths to reduce parasitic inductance. For high-current gate drive, use wide traces for VOA and VOB outputs to handle 4A peak currents.
Maintain proper isolation spacing between the input and output sides of the PCB to meet safety standards. The ADUM4223ARWZ provides 5000Vrms isolation, so the PCB must have adequate creepage and clearance distances. Refer to IPC-2221 for spacing guidelines based on working voltage.
The ADUM4223ARWZ dissipates power during switching due to gate charge losses. Ensure adequate thermal management by providing copper pour areas on the PCB and using thermal vias if necessary. The SOIC-16 package has a thermal resistance of approximately 100Β°C/W, so keep the junction temperature below 150Β°C.
Compliance Information
