ADUM3223WBRZ

Isolators - Gate Drivers Overview

The ADUM3223WBRZ is a galvanically isolated precision half-bridge gate driver utilizing iCoupler magnetic coupling technology. It features two independent channels with a peak output current of 4A and operates within a supply voltage range of 7.5V to 18V. The device provides 3000Vrms isolation and achieves a common mode transient immunity of 50kV/µs. Typical propagation delays are 54ns for both high-to-low and low-to-high transitions, with rise and fall times of 12ns. It is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Employs iCoupler magnetic coupling technology for galvanic isolation without transformers or optocouplers
• Provides high common mode transient immunity of 50kV/µs for reliable operation in noisy environments
• Delivers precise half-bridge driving capability with symmetric rise and fall times

Isolators - Gate Drivers Applications

• Isolated power supply control circuits
• Motor drive systems requiring high-speed switching
• Industrial automation inverters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix (e.g., WBRZ) against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm availability through authorized distributors as supply may be restricted. Ensure the selected packaging matches the intended assembly process requirements.

Isolators - Gate Drivers Selection Notes

Select this component when high isolation voltage and fast switching speeds are required for half-bridge topologies. Consider the 4A peak current capability for driving medium-power MOSFETs or IGBTs. Evaluate the 16-SOIC footprint against board space constraints and thermal management needs.

Isolators - Gate Drivers Part Context

This part belongs to the ADuM3223 series of isolated gate drivers. It is distinct from the ADUM4223 series which offers higher isolation ratings. The WBRZ suffix indicates a specific tape-and-reel or tube packaging variant compliant with lead-free standards.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other parts within the ADUM3223 family such as ADUM3223ARZ or ADUM3223BRZ, provided the package and suffix match. Cross-family replacements like ADUM4223 require verification of isolation voltage differences.
