Key Differentiators
- Automotive-grade option available (vs ADUM3223ARZ)
- Higher output current than ADUM3223 (vs ADUM3223ARZ)
- Faster propagation delay than Si8233 (vs Si8233BB-D-IS1)
Design Notes
For optimal performance, place the ADUM3224ARWZ close to the power switches to minimize gate drive loop inductance. Use separate ground planes for the input and output sides, and connect them only at the isolation barrier. Place 0.1 uF decoupling capacitors close to VDD1, VDDA, and VDDB pins to ensure stable supply voltages.
The ADUM3224ARWZ dissipates power primarily during switching. At 4 A peak output and high switching frequencies, ensure adequate PCB copper area for heat dissipation. The junction-to-ambient thermal resistance (theta_JA) is approximately 100Β°C/W; keep the junction temperature below 150Β°C by providing sufficient thermal vias and copper pour.
Do not exceed the absolute maximum ratings for VDD1 (6 V) and VDDA/VDDB (20 V). Ensure the input signals have fast rise/fall times to avoid excessive propagation delay. Also, avoid floating the input pins; tie unused inputs to GND1. Refer to the datasheet for proper power-up sequencing to prevent latch-up.
