Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the official Melexis datasheet to confirm pinout, flash configuration, and pre-programmed firmware options. Ensure compatibility with the target LIN bus baud rate and voltage requirements before finalizing procurement specifications.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring dual RGB LED control via a single LIN node. The 48 mA per channel output current supports standard automotive LEDs. Verify that the system architecture utilizes the bus shunt method for autoconfiguration if low pin count integration is required.

Application Specific Microcontrollers Part Context

The MLX81115 belongs to Melexis' family of smart LED drivers specifically engineered for automotive environments. It serves as a cost-effective solution for dynamic lighting by integrating communication, processing, and power driving capabilities into a single compact DFN4x4 package.

Application Specific Microcontrollers Replacement Considerations

Consult the official Melexis selection guide for direct functional equivalents or next-generation replacements such as the MLX81123 or MLX81124, which offer updated feature sets or different packaging options while maintaining LIN RGB control functionality.
