MLX81113KLW-BAB-000-SP

Application Specific Microcontrollers Overview

The MLX81113KLW-BAB-000-SP 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 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. Electrical specifications include an operating voltage range of 4.5 V to 18 V, a maximum operating temperature of +125 °C, and a minimum of -40 °C.

Application Specific Microcontrollers Feature Summary

• Integrated 16-bit pipelined RISC MCU with 32 kByte Flash, 2 kByte RAM, and 576 Byte EEPROM
• Four configurable constant current sources (up to 60 mA) for RGB+W LED control
• LIN 2.x and SAE J2602 compliant transceiver with autoaddressing support
• DFN-WF-10 (3x3 mm) package with exposed pad

Application Specific Microcontrollers Applications

• Automotive interior ambient lighting modules
• Door trim illumination systems
• Vehicle cabin accent lighting

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'SP' against official Melexis documentation to confirm packaging type, as standard variants often utilize 'RE' for reels. Confirm that the DFN-WF-10 package matches the required PCB footprint. Ensure compliance with AEC-Q100 qualification requirements for the target automotive environment.

Application Specific Microcontrollers Selection Notes

Select this component when a cost-effective LIN slave solution is required for single-node or simple multi-node ambient lighting setups. The MLX81113 supports ASIL-A safety integration. For higher channel counts or MeLiBu communication, consider the MLX81143 series instead.

Application Specific Microcontrollers Part Context

This part belongs to the MLX81113 family of LIN RGB controllers. The 'KLW' designation indicates the DFN-WF-10 3x3 mm package variant. The 'BAB' suffix typically denotes specific electrical characteristics or binning within the family, while 'SP' indicates sample or bulk packaging distinct from the standard reel configuration.

Application Specific Microcontrollers Replacement Considerations

The MLX81123 is the next-generation successor to the MLX81113, offering similar functionality with updated features. Direct pin-to-pin replacements within the same package should be verified against the latest datasheets.
