ADUM4223ARWZ - 4A Isolated Half-Bridge Gate Driver | Analog Devices
MPN: ADUM4223ARWZ ✓ AktifADUM4223ARWZ Ringkasan
An isolated gate driver is a specialized integrated circuit that provides the necessary voltage and current to drive the gate of a power transistor (such as a MOSFET or IGBT) while maintaining galvanic isolation between the control side and the power side. This isolation is critical in applications where the power stage operates at high voltages or where ground potential differences exist, preventing noise and protecting low-voltage control circuitry. The ADUM4223ARWZ uses magnetic coupling (iCoupler) instead of optocouplers, offering faster propagation delays, better timing accuracy, and higher reliability over temperature and lifetime.
Key features of the ADUM4223ARWZ include 4 A peak output current, 5000 Vrms isolation voltage, 38 ns propagation delay, and a wide operating temperature range of -40°C to +125°C. The device also features under-voltage lockout (UVLO) on both input and output supplies, ensuring safe operation during power-up and brown-out conditions. The iCoupler technology provides excellent common-mode transient immunity (CMTI) of 100 kV/us, which is essential for robust operation in noisy industrial environments.
The ADUM4223ARWZ is designed for high-performance isolated power conversion. Its architecture integrates a high-speed CMOS interface with monolithic transformer technology, eliminating the need for external components such as pulse transformers or optocouplers. The device supports both high-side and low-side drive with independent inputs, allowing flexible control of half-bridge topologies. The output stage can source and sink 4 A, enabling fast switching of large gate capacitances.
Typical applications include isolated switch-mode power supplies (SMPS), motor drives, solar inverters, and industrial power systems. The device is also suitable for automotive applications when using the AEC-Q100 qualified variant (ADUM4223WCRWZ). The high isolation rating and fast propagation delay make it ideal for high-frequency power converters where efficiency and reliability are paramount.
When designing with the ADUM4223ARWZ, ensure proper PCB layout to minimize parasitic inductance and maintain isolation spacing. The input and output supplies should be decoupled with low-ESR ceramic capacitors placed close to the pins. The device's UVLO feature helps prevent insufficient gate drive during startup, but designers should verify that the supply voltages meet the UVLO thresholds under all conditions.

Catatan Desain
Place decoupling capacitors (0.1uF and 10uF) close to VDD1 and VDD2 pins to ensure stable supply voltages. Use low-ESR ceramic capacitors and minimize trace lengths to reduce parasitic inductance. For high-current gate drive, use wide traces for VOA and VOB outputs to handle 4A peak currents.
Maintain proper isolation spacing between the input and output sides of the PCB to meet safety standards. The ADUM4223ARWZ provides 5000Vrms isolation, so the PCB must have adequate creepage and clearance distances. Refer to IPC-2221 for spacing guidelines based on working voltage.
The ADUM4223ARWZ dissipates power during switching due to gate charge losses. Ensure adequate thermal management by providing copper pour areas on the PCB and using thermal vias if necessary. The SOIC-16 package has a thermal resistance of approximately 100°C/W, so keep the junction temperature below 150°C.
