MAX16839ATT+T

LED Driver IC Overview

The MAX16839ATT+T is a high-voltage, linear LED driver IC designed for high-brightness lighting applications. It operates within an input voltage range of 5 V to 40 V and provides a single output channel with a maximum current of 100 mA. The device supports PWM dimming control and features open LED protection. It is qualified under AEC-Q100 standards for automotive use and functions reliably across a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates linear regulation for high-voltage LED driving
• Supports precise PWM dimming control
• Includes open LED protection circuitry

LED Driver IC Applications

• Automotive exterior lighting systems
• High-brightness general illumination
• Signage and display backlighting

LED Driver IC Procurement Notes

Verify the specific suffix (ATT+T) against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding the TDFN-EP-6 footprint. Confirm that the AEC-Q100 qualification meets your specific automotive reliability requirements before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a compact solution for high-voltage LED strings is required without external switching inductors. It is suitable for designs needing linear regulation simplicity with integrated protection features. Consider the 100 mA output limit and thermal dissipation capabilities relative to the target LED load and ambient operating conditions.

LED Driver IC Part Context

This part belongs to the MAX16839 family of high-voltage linear LED drivers from Maxim Integrated. It is distinct from other variants like the MAX16839EVKIT+, which is an evaluation kit rather than the standalone driver IC. The ATT+T designation specifies the automotive-grade, tape-and-reel packaged version of the core MAX16839A controller.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives within the MAX1683x series or comparable high-voltage linear drivers from other manufacturers. Verify that any substitute maintains the same 40V input rating, 100mA output capability, and AEC-Q100 automotive qualification if used in vehicle applications.
