MLX81113KDC-BAB-000-RE

Application Specific Microcontrollers Overview

The MLX81113KDC-BAB-000-RE is a fully integrated low-end LIN slave controller designed for automotive ambient lighting applications. It drives RGB LEDs via the LIN bus, combining a physical layer LIN transceiver, protocol controller, and current-controlled outputs. 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 LIN 2.x and SAE J2602 standards.

• LIN bus-connected RGB LED drivers

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel quantity. The 'RE' suffix typically indicates tape-and-reel packaging, while 'KDC' denotes the SOIC8EP package variant. Confirm export control requirements and AEC-Q100 qualification status prior to integration into safety-critical designs.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring a cost-effective, single-chip solution for controlling multiple RGB LEDs over a LIN network. Ensure the design accommodates the 60 mA per channel limit and utilizes the internal 10-bit ADC for battery monitoring if required. Compare against the MLX81114 if memory access protection features are necessary for anti-theft applications.

Application Specific Microcontrollers Part Context

The MLX81113 series serves as a foundational LIN RGB controller from Melexis, enabling simple yet powerful ambient light modules. It bridges the gap between standard microcontrollers and dedicated LED drivers by integrating the LIN physical layer directly on-chip. This integration reduces external component count and simplifies PCB layout for automotive OEMs developing customizable interior lighting environments.

Application Specific Microcontrollers Replacement Considerations

The MLX81114 offers similar functionality but includes memory access protection options suitable for anti-theft applications. For higher channel counts or advanced color mixing, consider the MLX81143. Verify pin compatibility and software driver availability when transitioning between these variants.
