Product details
Overview
MLX81113KLW-BBC-000-SP from Melexis is a fully integrated automotive-grade LIN slave IC for RGB+W LED ambient lighting control, featuring a 16-bit RISC microcontroller, LIN 2.x/J2602 transceiver, four 60 mA current-controlled outputs, 4×16-bit PWM, and diagnostic capability for open/short LED detection. It operates across −40 °C to +125 °C and supports autoaddressing via bus shunt method in vehicle cabin lighting modules.
For engineers reviewing the MLX81113KLW-BBC-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include LIN protocol compliance (SAE J2602), integrated current sources for RGB+W channels, diagnostic coverage for LED faults, sleep-mode current (25 µA typ), and AEC-Q100 qualification for under-hood and interior lighting systems.
Technical Context
The MLX81113KLW-BBC-000-SP integrates a LIN protocol controller and physical-layer transceiver compliant with LIN 2.x and SAE J2602, supporting up to 19.2 kBaud with frame processing and low interrupt overhead. Its 16-bit pipelined RISC core runs at up to 16 MHz and includes 32 kB Flash, 2 kB RAM, and 512 B EEPROM with system ROM bootloader.
Four high-voltage I/Os serve as configurable current sources (0–60 mA) for RGB+W LED driving, each paired with dedicated 16-bit PWM generators offering adjustable resolution. On-chip diagnostics monitor LED continuity and threshold violations, while the 10-bit ADC with DMA supports temperature sensing, battery monitoring (over/under-voltage), and VS rail measurement.

The MLX81113KLW-BBC-000-SP firmware includes a certified LIN stack in system ROM, enabling immediate integration into automotive networks without additional protocol development.
Does the MLX81113KLW-BBC-000-SP support RGB+W LED configurations?
Yes, the MLX81113KLW-BBC-000-SP provides four independent high-voltage current sources (LC0–LC3), each programmable from 0 to 60 mA, enabling direct drive of red, green, blue, and white LEDs. Each channel pairs with a dedicated 16-bit PWM generator for precise color mixing and dimming. The MLX81113KLW-BBC-000-SP's current matching and thermal compensation ensure stable chromaticity across temperature and supply variations.
What diagnostic capabilities does the MLX81113KLW-BBC-000-SP provide for connected LEDs?
The MLX81113KLW-BBC-000-SP performs per-channel LED diagnostics including open-circuit detection, short-to-VBat or GND, and current threshold violation reporting. These diagnostics operate autonomously during normal operation and sleep mode wake-up events. Results are accessible via LIN diagnostic services, and the MLX81113KLW-BBC-000-SP can trigger error frames or enter safe state if critical faults are detected - fulfilling ASIL-A requirements for ambient lighting safety.
Is the MLX81113KLW-BBC-000-SP qualified for automotive use?
Yes, the MLX81113KLW-BBC-000-SP is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C) and developed according to ISO 26262 for ASIL-A safety integrity level. It includes watchdog timers with independent clocks, memory ECC (in Flash and EEPROM), and built-in self-test routines. The MLX81113KLW-BBC-000-SP also meets 28 V jump-start tolerance and reverse-battery protection requirements defined in automotive OEM specifications.
What package type and thermal performance does the MLX81113KLW-BBC-000-SP use?
The MLX81113KLW-BBC-000-SP uses an SOIC8 package with exposed thermal pad, optimized for surface-mount assembly and heat dissipation in confined lighting modules. The exposed pad improves thermal resistance to PCB (typically <40 °C/W junction-to-board), allowing sustained 60 mA output per channel at 125 °C ambient. Pin-compatible DFN10 variants exist but the MLX81113KLW-BBC-000-SP specifically uses SOIC8 for mechanical robustness and reworkability in automotive production.
