MLX81113KLW-BAB-000-RE

Application Specific Microcontrollers Overview

The MLX8113KLW-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 transceiver, protocol controller, and current-controlled outputs. The device features a 16-bit RISC microcontroller with 32 kB Flash, 2 kB RAM, and 576 B EEPROM. It includes four high-voltage I/Os capable of sourcing up to 60 mA each, supporting RGB+W configurations. Operating within an automotive temperature range of -40°C to +125°C, it meets AEC-Q100 standards and supports LIN 2.x and SAE J2602 protocols.

Application Specific Microcontrollers Feature Summary

• Integrated 16-bit RISC MCU with 32 kB Flash, 2 kB RAM, and 576 B EEPROM
• Four configurable constant current sources (up to 60 mA) for RGB+W LED control
• LIN 2.x and SAE J2602 compliant transceiver with auto-addressing support
• Diagnostic capabilities for short circuit, open load, and threshold monitoring

Application Specific Microcontrollers Applications

• Automotive interior ambient lighting modules
• Door trim illumination systems
• Vehicle cabin accent lighting
• Multi-node LIN bus RGB LED arrays

Application Specific Microcontrollers Procurement Notes

Verify package type DFN-WF-10 (3x3 mm) matches design requirements. Confirm supply chain lead times as production cycles may vary. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Validate that the reel packaging quantity aligns with manufacturing line capacities.

Application Specific Microcontrollers Selection Notes

Select this model for designs requiring the compact DFN-WF-10 footprint instead of the SOIC-8 variant. Ensure the application utilizes LIN 2.x or SAE J2602 bus architectures. Verify that the 60 mA per channel output current suffices for the target LED load. Check compatibility with existing bootloader and LIN driver software in the system ROM.

Application Specific Microcontrollers Part Context

This component belongs to the MLX81113 family of LIN RGB controllers from Melexis. It serves as a dedicated slave node for controlling color-changing ambient lights in vehicles. The KLW suffix denotes the specific DFN-WF-10 package option, distinguishing it from other package variants like the DC (SOIC-8) version within the same functional series.

Application Specific Microcontrollers Replacement Considerations

Direct replacements include other MLX81113 variants with different packages, such as MLX81113KDC-BAB-000-RE (SOIC-8). Ensure pinout compatibility and thermal performance differences between DFN-WF-10 and alternative packages are evaluated before substitution.
