LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'V+' indicates lead-free compliance and RoHS adherence. Ensure the TDFN-EP-6 package matches your PCB footprint requirements. Check current availability status as supply may be restricted. Validate that the AEC-Q100 qualification meets your specific automotive grade requirements.

LED Driver IC Selection Notes

Select this component when a linear solution is preferred for simplicity in high-voltage LED strings. The 100 mA output current limits its use to lower-power LED arrays compared to higher-current drivers. Consider the thermal dissipation capabilities of the TDFN-EP-6 package for your specific ambient temperature conditions. Verify compatibility with your system's PWM dimming frequency specifications.

LED Driver IC Part Context

This part belongs to the MAX16839 series from Maxim Integrated, now part of Analog Devices. It is distinct from the MAX16831, which offers higher voltage tolerance and different packaging. The EVKIT+ serves as the official evaluation platform for this family, facilitating design-in for engineers developing LED lighting solutions requiring automotive-grade linear drivers.

LED Driver IC Replacement Considerations

Direct substitutes include other parts within the MAX16839 family such as the MAX16839ATT+T. Cross-reference pinouts and electrical characteristics carefully. No alternative part numbers are explicitly confirmed as direct replacements in the provided documentation.
