MAX20088ATPA/VY+

Current Regulation/Management Overview

The MAX20088ATPA/VY+ is an automotive-grade current switch and regulator manufactured by Analog Devices Inc./Maxim Integrated. It provides a regulated output current of 600mA with ±8% accuracy. The device operates from a supply voltage range of 3V to 15V and features a 20-TQFN-EP (4x4) surface-mount package with wettable flanks for enhanced inspection. It is qualified under AEC-Q100 standards and supports an operating temperature range of -40°C to 125°C.

Current Regulation/Management Feature Summary

• Provides precise current regulation with specified accuracy tolerance
• Supports wide input voltage operation suitable for automotive environments
• Features a thermally enhanced package with visible solder joints

Current Regulation/Management Applications

• Automotive exterior lighting systems
• Interior ambient lighting control
• LED driver circuits in vehicle electronics

Current Regulation/Management Procurement Notes

Verify the specific suffix 'VY+' indicates the presence of wettable flanks on the package leads, which facilitates automated optical inspection. Confirm that the 'A' designation corresponds to the extended industrial/automotive temperature range. Ensure the component matches the required 20-TQFN-EP footprint dimensions during PCB layout verification.

Current Regulation/Management Selection Notes

Select this component when a robust, single-channel current source is required for automotive LED applications. The integrated regulation simplifies thermal management compared to discrete solutions. Consider the ±8% accuracy sufficient for general illumination rather than precision color-critical tasks requiring tighter tolerances.

Current Regulation/Management Part Context

This part belongs to the MAX2008x family of automotive current switches. It shares functional similarities with the MAX20087 but may differ in specific pin configurations or internal protection features. The family is designed to replace discrete transistor-based drivers in modern vehicle lighting architectures.

Current Regulation/Management Replacement Considerations

Direct substitutes include other members of the MAX2008x series such as the MAX20087ATPA/VY+T. Verify pin-to-pin compatibility and ensure the replacement maintains the same AEC-Q100 qualification status and package thermal characteristics.
