ADUM3220BRZ-RL7

Isolators - Gate Drivers Overview

The ADUM3220BRZ-RL7 is a dual-channel, galvanically isolated gate driver manufactured by Analog Devices Inc. It features magnetic coupling technology for signal transmission across the isolation barrier. The device provides a peak output current of 4 A per channel and operates with a nominal undervoltage lockout (UVLO) threshold of 7 V. It supports supply voltages ranging from 3.3 V to 5 V on the input side and up to 18 V on the output side. The component is housed in an 8-SOIC package and is designed for surface mount installation. It ensures reliable operation within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the manufacturer part number matches ADUM3220BRZ exactly. Check datasheet revisions for any pinout or electrical parameter updates. Ensure the supplier provides valid RoHS compliance documentation. Validate that the component meets the required operating temperature range for the intended application environment.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation is required without external transformers. Consider the 4 A peak current rating against the load capacitance requirements. Verify that the system voltage does not exceed the 18 V maximum output supply limit. Ensure the PCB layout accommodates the 8-SOIC package dimensions. Evaluate the need for the specific UVLO threshold relative to the target MOSFET or IGBT gate voltage levels.

Isolators - Gate Drivers Part Context

This part belongs to the ADUM3220 series of digital isolators and gate drivers. It utilizes Analog Devices' iCoupler technology for signal transmission.
