ADUM4221ARIZ-RL

Gate Driver Overview

The ADUM4221ARIZ-RL is a current-isolated half-bridge gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 6.5 V and delivers a peak output current of 4 A. The device features symmetric rise and fall times of 25 ns and supports both inverting and non-inverting configurations. It is housed in a 16-lead SOIC package and functions reliably across an operating temperature range from -40 °C to +125 °C.

Gate Driver Feature Summary

• Integrates magnetic coupling technology for galvanic isolation between input and output circuits
• Includes built-in under-voltage lockout (UVLO) mechanisms to ensure stable operation during power transitions
• Provides precise dead-time control to prevent shoot-through currents in half-bridge topologies

Gate Driver Applications

• Industrial motor drive systems requiring isolated gate control
• Inverter circuits in renewable energy conversion equipment
• High-frequency switching power supplies with isolated secondary sides

Gate Driver Procurement Notes

Verify the specific suffix 'ARIZ-RL' against official Analog Devices documentation to confirm package type, tape-and-reel quantity, and regional availability status. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when designing half-bridge drivers that require high common-mode transient immunity and integrated dead-time management. Ensure the application demands a 4 A peak drive capability and operates within the specified 2.5 V to 6.5 V supply range. Confirm that the SOIC-16 footprint aligns with the target PCB layout constraints.

Gate Driver Part Context

This part belongs to the ADUM422x series of current-isolated gate drivers from Analog Devices. These devices utilize iCoupler technology to provide robust signal transmission across isolation barriers without relying on traditional transformers or optocouplers, offering improved reliability and smaller form factors compared to legacy solutions.

Gate Driver Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives such as the ADUM4223 or ADUM4224 series. Verify pin compatibility and electrical specifications before replacing the component to maintain system integrity.
