Automotive-grade isolated gate driver for traction inverters and motor drives
The Analog Devices ADUM3224WCRZ-RL7 is a 2-channel isolated gate driver using magnetic coupling technology, rated for 3000Vrms isolation and delivering 4A peak output current. It is qualified to Automotive grade, making it suitable for under-hood and chassis-domain applications such as traction inverters, DC-DC converters, and on-board chargers in hybrid and electric vehicles.
The 4A peak output current provides the gate charge needed to switch large power devices quickly, reducing switching losses in high-frequency designs. The 12ns rise and fall times complement this by minimizing the time spent in the linear region. The 25kV/µs common-mode transient immunity ensures the driver rejects fast voltage transients across the isolation barrier — critical in motor-drive environments where high dv/dt events from the inverter stage can otherwise cause false triggering or latch-up. Propagation delay is specified at 54ns max, which is typical for this class of isolated driver and should be budgeted in dead-time calculations.
Active lifecycle and packaging variant
It is ROHS3 compliant. The device is housed in a 16-SOIC narrow-body package (0.154", 3.90mm width), a standard footprint that simplifies PCB layout and second-sourcing.
