ADUM4221-1BRIZ-RL

Gate Driver Overview

The ADUM4221-1BRIZ-RL is a current-isolated gate driver featuring an integrated PWM input and UVLO, manufactured by Analog Devices Inc. It utilizes capacitive coupling technology to provide galvanic isolation between the primary and secondary sides of the circuit. The device is housed in a 16-pin SOIC package and supports surface-mount installation. It operates within a temperature range of -40°C to +125°C with a maximum power dissipation of 2.77 W. Key electrical parameters include a maximum propagation delay of 44 ns, a rise time of 25 ns, and a fall time of 25 ns.

Gate Driver Feature Summary

• Integrates a PWM input stage for direct signal interfacing
• Provides robust galvanic isolation via capacitive coupling technology
• Includes under-voltage lockout (UVLO) functionality for reliable operation

Gate Driver Applications

• Isolated gate driving for power switches
• Industrial motor control systems
• Power supply designs requiring isolated feedback or control loops

Gate Driver Procurement Notes

Verify availability status as this part number may be subject to limited supply conditions or factory special orders. Confirm that the specific suffix matches the required reel packaging configuration. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement plans.

Gate Driver Selection Notes

Select this component when high-speed isolation with integrated PWM decoding is required. Consider the 44 ns propagation delay and 25 ns switching times for timing-sensitive applications. Verify that the SOIC-16 package fits the design constraints and that the operating temperature range meets environmental specifications.

Gate Driver Part Context
