LED Driver IC Applications

• Automotive lighting systems
• General-purpose LED signage
• High-brightness LED illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'ASA+' against official datasheets to confirm pinout and thermal pad configuration. Confirm RoHS compliance status through manufacturer documentation. Check availability as distribution may vary. Ensure the selected component matches the required input voltage and current specifications for the target design.

LED Driver IC Selection Notes

Select this component for designs requiring linear regulation of high-brightness LEDs from high-voltage sources. It is appropriate where simplicity and robustness against load dump events are prioritized over efficiency. Verify that the 100 mA output current meets the LED string requirements and that the 8-SOIC-EP package fits the PCB layout constraints.

LED Driver IC Part Context

This part belongs to the MAX16839 family of high-voltage linear LED drivers. It is distinct from switching regulators like the MAX16836, offering a simpler solution for lower power or specific voltage drop scenarios. The device is intended for direct drive applications without complex external feedback networks.

LED Driver IC Replacement Considerations
