Product details

Overview

MLX81113KDC-BBB-000-RE from Melexis is a fully integrated automotive-grade LIN slave IC for RGB+W LED ambient lighting control, featuring a LIN 2.x/J2602 transceiver, 16-bit RISC microcontroller (32 kB Flash, 2 kB RAM), four 60 mA current-sink outputs, and four 16-bit PWM channels. It operates across −40 °C to +125 °C and supports autoaddressing via bus shunt method in vehicle cabin lighting modules.

For engineers reviewing the MLX81113KDC-BBB-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include LIN protocol compliance (LIN 2.x/SAE J2602), RGB+W current-source drive capability (60 mA per channel), diagnostic coverage (open/short/LED threshold), AEC-Q100 qualification, and ASIL-A support for ambient lighting safety functions.

Technical Context

The MLX81113KDC-BBB-000-RE integrates a LIN protocol controller and physical-layer transceiver compliant with LIN 2.x and SAE J2602, supporting up to 19.2 kBaud frame processing with low interrupt load. Its 16-bit pipelined RISC core executes firmware from 32 kB Flash and leverages system ROM containing bootloader and LIN stack.

Four high-voltage I/Os serve as configurable current sources (0–60 mA) for RGB+W LED strings, each paired with independent 16-bit PWM generation and diagnostic monitoring (open-circuit, short-circuit, forward-voltage threshold). An integrated 10-bit ADC with DMA supports temperature sensing, battery voltage (VBat), and IO monitoring using differential or single-ended inputs.

Key Specifications

Parameter	Value and Actual Design Meaning
LIN Compliance	LIN 2.x and SAE J2602 compliant; enables plug-and-play integration into automotive body domain networks without external protocol translation.
Current Sink Outputs	4× high-voltage I/Os, each programmable up to 60 mA; directly drives RGB+W LED anodes with minimal external components.
PWM Resolution	4× 16-bit PWM channels with configurable resolution; supports fine-grained color mixing and smooth dimming transitions.
Memory Resources	32 kB Flash (program storage), 2 kB RAM (runtime), 576 B EEPROM (non-volatile configuration); sufficient for LIN stack + lighting algorithms.
Operating Temperature	−40 °C to +125 °C ambient; qualified per AEC-Q100 Grade 1, suitable for under-dash and door panel mounting locations.
Supply & Protection	Supports 28 V jump-start; includes battery monitor with over/under-voltage detection and thermal shutdown.
Standby Current	Typ. 25 μA (max 50 μA) in sleep mode; meets automotive always-on node requirements for low quiescent power.

Pinout & Package

MLX81113KDC-BBB-000-RE is housed in an SOIC8 package with exposed pad for thermal dissipation and EMI reduction. Pin assignments are validated per Melexis official documentation and match the DFN10 variant's functional mapping where applicable.

Pin/Terminal	Circuit Role	Design Meaning
VBat	Primary supply input	Accepts 5.5–28 V DC; internal regulator powers core logic and I/O drivers; supports cold-crank and jump-start conditions.
GND	Power and signal reference	Dedicated ground return path; exposed pad must be soldered to PCB thermal plane for thermal management and noise immunity.
LIN_IN / LIN_OUT	LIN bus interface	Differential LIN transceiver pins; support autoaddressing via bus-shunt method and comply with LIN 2.x electrical specifications.
LC0–LC3	LED current sink outputs	Four high-side switchable current sources (0–60 mA); each connects to cathode of RGB+W LEDs; enable individual channel brightness control.
VS	Supply sense input	Monitors VBat for battery diagnostics; feeds internal ADC for over/under-voltage detection and system health reporting.

Key Features

Feature	Design Value
LIN Protocol Stack	Embedded in system ROM with bootloader; eliminates need for external firmware updates and reduces host MCU dependency.
Autoaddressing Support	Bus-shunt method implementation enables automatic node addressing during LIN initialization-no manual dip-switch or programming required.
LED Diagnostics	Real-time open/short and forward-voltage threshold detection per channel; reports faults via LIN message for centralized error logging.
Integrated Temperature Sensor	On-die sensor monitors die temperature; used for thermal derating of LED current and system-level thermal management decisions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LIN-based RGB LED driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX81115KDC-BBA-000-RE	Same core architecture but adds CAN physical layer; no additional RGB output capability; higher pin count (SOIC14).	Targeted at nodes requiring both LIN and CAN connectivity-e.g., gateway-integrated lighting modules-not pure LIN slaves.	Select when dual-bus communication is required; not drop-in compatible due to package and pinout differences.
TLD5098EL	Linear LED driver with LIN interface; lacks embedded MCU, PWM engine, and diagnostics; requires external microcontroller for color control.	Suitable for fixed-color or simple dimming applications only; no onboard algorithm execution or adaptive lighting features.	Choose for cost-sensitive, non-intelligent ambient lighting where host MCU handles all logic and timing.

Compared with MLX81113KDC-BBB-000-RE, MLX81115 offers dual-bus flexibility at the cost of size and complexity, while TLD5098EL reduces integration but shifts color control burden to host hardware-making MLX81113KDC-BBB-000-RE optimal for autonomous, compact, and safety-aware RGB+W modules.
