Product details

The ADUM3220WARZ from Analog Devices is an isolated dual-channel gate driver rated for 4 A peak output per channel, designed to drive power MOSFETs and IGBTs in half-bridge and full-bridge topologies. Its isolation barrier supports motor drives, industrial inverters, and switched-mode power supplies where galvanic isolation between the low-voltage control side and high-voltage power stage is mandatory.

The 4 A peak drive current is the headline spec that determines how fast the gate capacitance of the external power switch charges and discharges. For a typical IGBT or MOSFET with a gate charge of 100 nC, a 4 A source delivers a rise time around 25 ns, which keeps switching losses low in hard-switched converters running at 50–100 kHz. The dual-channel configuration lets you drive the high-side and low-side switches of a half-bridge with matched propagation delays, avoiding shoot-through from timing mismatch.

If your line expects tape, you will need to transfer to a compatible carrier or order a different packing option.

Frequently asked questions

What is the output current of ADUM3220WARZ?

The ADUM3220WARZ is rated for 4 A peak output current per channel, making it suitable for driving medium-to-large power MOSFETs and IGBTs in isolated gate-drive applications.

What is the ADUM3220WARZ equivalent or replacement?

The closest functional sibling is the ADUM3200WARZ, which shares the same package and isolation rating but is not rated for 4 A output. The ADUM3220WARZ is the higher-drive variant in the same family. No direct pin-compatible replacement with identical 4 A drive is listed as a second source.
