Key Differentiators
- 4 A peak output current (vs ADUM3223ARZ-RL7)
- 3000 Vrms isolation (vs ADUM4223ARWZ-RL7)
- Automotive grade option (vs ADUM3223WBRZ-RL7)
Design Notes
Place decoupling capacitors (0.1 Β΅F and 10 Β΅F) 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 gate drive loop (output to MOSFET gate and source) as short as possible to reduce ringing and overshoot.
The ADUM3223ARWZ-RL7 can dissipate significant power when driving large capacitive loads at high frequencies. Ensure adequate PCB copper area for heat dissipation, especially under the SOIC package. For high ambient temperatures, consider derating the output current or adding thermal vias to improve heat transfer.
Avoid exceeding the absolute maximum ratings for supply voltages and output current. Ensure that the input signals (VIA, VIB) are properly referenced to GND1 and have sufficient pulse width to meet the minimum input pulse requirement. Also, be aware of the propagation delay mismatch between channels, which can cause shoot-through in half-bridge configurations; adjust dead time accordingly.
