Key Differentiators
- Automotive-grade variant available (vs ADUM3224ARWZ-RL7)
- Higher isolation option (vs ADUM4224ARWZ-RL7)
- Same package and pinout across variants (vs ADUM3224BRZ-RL7)
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 solid ground plane for VSS1 and VSS2 to minimize noise. Keep the gate drive loop (output pins to MOSFET gate) as short as possible to reduce parasitic inductance and ringing.
The ADUM3224ARWZ-RL7 can dissipate significant power when driving large gate capacitances at high frequencies. Ensure adequate copper area on the PCB for heat dissipation. The thermal resistance of the SOIC package is moderate; for high-frequency operation, consider adding thermal vias under the package to improve heat transfer to the ground plane.
Do not exceed the absolute maximum ratings for supply voltage (18 V) or output current. Ensure that the input signals are within the specified logic levels to avoid damage. Also, be aware of the UVLO threshold; the device will not operate correctly if the supply voltage is below the UVLO level. Always refer to the datasheet for complete operating conditions.
