MLX81113KDC-BAB-000-SP

Application Specific Microcontrollers Overview

The MLX81113KDC-BAB-000-SP is a fully integrated low-end LIN slave designed for automotive ambient lighting applications. It combines a physical layer LIN transceiver, a LIN protocol controller compliant with LIN 2.x and SAE J2602 standards, and current-controlled outputs to drive RGB LEDs. The device features a 16-bit pipelined RISC microcontroller with 32 kByte Flash, 2 kByte RAM, and 576 Byte EEPROM. It includes four high-voltage I/Os capable of sourcing up to 60 mA each, supporting RGB+W configurations. The IC operates within an automotive temperature range of -40 °C to +125 °C and supports 28 V jump start.

Application Specific Microcontrollers Procurement Notes

Verify the specific package variant against project requirements, as the MLX81113 series is available in both SOIC-8EP and DFN-WF-10 packages. Confirm that the selected part number aligns with the required memory configuration and output current specifications. Ensure compliance with export regulations if applicable, as authorization may be required for certain shipments. Cross-reference the latest datasheet for any updates to electrical parameters or pin assignments before finalizing procurement.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring a cost-efficient, single-chip solution for LIN-based RGB LED control. The MLX81113KDC-BAB-000-SP utilizes the SOIC-8EP package, which should be considered during PCB layout design due to its exposed pad thermal characteristics. Ensure the system power supply can handle the 28 V jump start requirement and that the LIN bus topology supports the autoaddressing feature if utilized. Verify that the 60 mA per channel output current meets the LED load requirements.

Application Specific Microcontrollers Part Context

The MLX81113KDC-BAB-000-SP belongs to the MLX81113 family of LIN RGB LED drivers from Melexis. This family is designed to simplify the development of ambient light modules by integrating the MCU, LIN interface, and LED drivers into a single chip. The 'KDC' suffix indicates the SOIC-8EP package option, distinguishing it from the DFN10 variant found in other parts like the MLX81113KLW series.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same family include the MLX81113KLW-BAB-000-RE, which offers identical functionality but in a DFN-WF-10 package. When substituting, verify that the footprint and thermal management strategies are compatible with the new package type. Other MLX8111x variants may offer different memory sizes or safety levels (e.g., ASIL-B) but require firmware adaptation.
