Key Differentiators
- Higher isolation voltage than ADUM3224 (vs ADUM3224ARWZ)
- Automotive grade option available (vs ADUM4224WARWZ)
- Faster propagation delay than UCC21520 (vs UCC21520DW)
Design Notes
Place decoupling capacitors (0.1 uF and 10 uF) close to the VDD1 and VDD2 pins to ensure stable supply voltages. Use a ground plane to minimize parasitic inductance in the gate drive loop. Keep the gate drive traces short and wide to reduce ringing and improve switching performance.
The ADUM4224ARWZ-RL7 can dissipate significant power when driving large capacitive loads at high frequencies. Ensure adequate copper area on the PCB for heat dissipation, and consider thermal vias under the device if operating at high ambient temperatures. The junction-to-ambient thermal resistance is [DATA_NEEDED: theta_JA].
Do not exceed the absolute maximum ratings for VDD1 and VDD2. Ensure the dead-time control pin is properly configured to prevent shoot-through current in the half-bridge. Avoid floating input pins; connect unused inputs to GND1 or VDD1 as appropriate.
Compliance Information
RoHS compliant per Analog Devices product page. Not AEC-Q100 qualified; choose ADUM4224WARWZ for automotive.
