Overview
The MLX81120KLW-AAD-100-RE is a fully integrated LIN-to-LIN gateway and RGB controller designed for automotive ambient lighting. It features a 16-bit MULAN MCU with 32 kB Flash, 16 kB ROM, and 2 kB RAM. The device includes two LIN transceivers compliant with LIN 2.x and SAE J2602 standards, supporting baud rates up to 19.2 kBaud. It provides four high-voltage I/Os capable of driving RGB+W LEDs with currents up to 48 mA, alongside four 16-bit PWM outputs. Operating on a supply voltage of 5.5 V to 18 V, it functions within an ambient temperature range of -40°C to +125°C.
Feature Summary
- Dual LIN Transceivers: Supports LIN-to-LIN gateway functionality with autoconfig capabilities.
- Integrated MCU: 16-bit architecture with 32 kB Flash, 16 kB ROM, and math co-processor.
- LED Drivers: Four configurable high-voltage I/Os (up to 48 mA) and four 16-bit PWM outputs.
- Diagnostic & Control: Includes 10-bit ADC with DMA, battery monitor, and LED diagnostic features.
Applications
- Automotive ambient lighting modules
- LIN-to-LIN bus extension gateways
- RGB+W LED color control systems
Procurement Notes
Verify the specific ordering suffix 'KLW-AAD-100-RE' against the manufacturer's current catalog to confirm package type and tape/reel specifications. Ensure design compliance with automotive environmental standards given the -40°C to +125°C operating range. Check for any end-of-life or not-for-new-designations in official distributor databases before finalizing procurement plans.
Selection Notes
Select this component when a dual-LIN interface is required for network expansion alongside RGB LED control. The 32 kB Flash allows for complex application logic storage. Verify that the DFN12 package fits the thermal and spatial constraints of the target PCB layout. Ensure the host system supports the LIN 2.x protocol and SAE J2602 requirements for proper integration.
Part Context
This part belongs to the MLX81120 series, which serves as a low-end LIN slave solution for automotive environments. It combines physical layer transceivers, protocol controllers, and current-controlled outputs to simplify the development of cost-effective ambient light modules connected to LIN bus systems.
Replacement Considerations
Consult Melexis documentation for direct pin-compatible alternatives within the MLX811xx family. Verify functional equivalence regarding memory size and I/O configurations if substituting with other LIN RGB controllers.
