Key Differentiators
- High isolation voltage of 5000Vrms (vs 1ED020I12-F2)
- Higher peak output current of 4A (vs 1ED020I12-F2)
- Wider output supply range (vs ISO5852S)
Design Notes
Ensure proper PCB layout for the ADUM4135BRWZ to minimize parasitic inductance and maintain signal integrity. Place decoupling capacitors (e.g., 0.1Β΅F and 10Β΅F) close to the VDD1 and VDD2 pins. Use a solid ground plane for GND1 and GND2, and keep the high-voltage output traces short and wide to handle high currents.
The ADUM4135BRWZ can dissipate significant power when driving large IGBTs at high frequencies. Ensure adequate thermal management by providing a copper pour on the PCB connected to the thermal pad (if exposed) and consider airflow or heatsinking in high-power applications. Monitor the junction temperature to stay within the -40Β°C to +125Β°C operating range.
A common pitfall is improper connection of the DESAT pin. The DESAT pin must be connected to the IGBT collector through a high-voltage diode and a resistor to set the blanking time. Failure to do so can result in false DESAT triggering or failure to detect overcurrent. Also, ensure the Miller clamp is connected to the gate to prevent false turn-on due to the Miller effect.
