ADUM4221BRIZ

Gate Driver Overview

The ADUM4221BRIZ is a current-isolated half-bridge gate driver manufactured by Analog Devices Inc. It integrates two drivers in a single SOIC-16 package, supporting both inverting and non-inverting configurations. The device operates on a supply voltage range of 2.5 V to 6.5 V and delivers a peak output current of 4 A. It features symmetric rise and fall times of 25 ns. The component is rated for an operating temperature range from -40°C to +125°C and includes under-voltage lockout (UVLO) functionality with integrated dead-time control.

Gate Driver Feature Summary

• Integrates dual-channel isolation technology within a compact surface-mount package
• Provides robust under-voltage lockout protection for reliable switching operations
• Supports configurable signal inversion or non-inversion logic states

Gate Driver Applications

• Isolated power supply gate driving
• Motor control systems requiring galvanic isolation
• Industrial automation inverters

Gate Driver Procurement Notes

Verify the specific suffix 'BRIZ' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS compliance status. Ensure that the SOIC-16 footprint matches your PCB design guidelines. Confirm moisture sensitivity level handling requirements during assembly to prevent package damage. Cross-reference the ordering part number with authorized distributors to ensure authenticity and traceability.

Gate Driver Selection Notes

Select this component when high-speed switching with precise timing symmetry is required in isolated environments. The 4 A output capability suits medium-power applications. Consider the 25 ns propagation delay for frequency constraints. Verify that the 6.5 V maximum supply voltage aligns with the target logic levels. Evaluate thermal performance within the specified -40°C to +125°C range for the intended enclosure.

Gate Driver Part Context

This device belongs to the ADuM422x series of current-isolated gate drivers. It utilizes Analog Devices' iCoupler technology to provide electrical isolation between input and output circuits. The series is designed for applications demanding high common-mode transient immunity and low power consumption compared to traditional magnetic isolators.

Gate Driver Replacement Considerations

Consult official substitution guides for compatible variants such as the ADUM4223WBRWZ. Verify channel count and isolation voltage ratings before swapping components.
