Overview
The ADUM3221WARZ-RL7 is an isolated dual-channel gate driver manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.3 V to 5 V and features a nominal undervoltage lockout (UVLO) of 4.1 V. The device provides an output current capability of 4.7 mA and utilizes silicon technology. It is housed in an SOIC-8 surface-mount package and is qualified under the AEC-Q100 standard for automotive applications. The component supports an operating temperature range from -40 C to +125 C.
Feature Summary
- Provides galvanic isolation for dual-channel signal transmission
- Includes integrated undervoltage lockout protection mechanism
- Complies with AEC-Q100 automotive qualification standards
Applications
- Automotive power electronics control systems
- Industrial motor drive gate driving
- Isolated interface for power management circuits
Procurement Notes
Verify the specific suffix RL7 indicates reel packaging configuration when sourcing. Confirm that the AEC-Q100 qualification status aligns with target automotive reliability requirements. Ensure the SOIC-8 footprint matches the design layout constraints. Check for any regional distribution restrictions or limited availability notices associated with this specific part number before finalizing procurement plans.
Selection Notes
Select this component when dual-channel isolation is required for gate driving applications. The 4.7 mA output current suits low-power switching scenarios. The wide operating temperature range supports harsh environments. Verify compatibility with 3.3 V or 5 V logic levels. Consider the SOIC-8 package size for board space limitations. Ensure UVLO thresholds meet system startup requirements.
Part Context
This part belongs to the ADuM322x series of isolated gate drivers from Analog Devices. It shares architectural similarities with the ADUM3220 but differs in channel configuration or specific electrical characteristics. The WARZ designation typically indicates a specific tape and reel packaging option. It serves as a solution for noise-immune control in power conversion systems.
Replacement Considerations
The ADUM3220WARZ-RL7 is a related variant within the same product family. Verify functional equivalence regarding channel count and output current specifications before substitution. Ensure pinout compatibility between the two parts to avoid redesign efforts.
