MLX81150LLW-DAA-000-RE

Overview

The MLX81150LLW-DAA-000-RE is a LIN slave controller designed for relay and DC motor control applications. It integrates an MLX16x8 16-bit RISC CPU with a co-processor, 32 kB Flash (with ECC), 2 kB RAM, and 380 B EEPROM. The device features an integrated LIN transceiver supporting LIN 2.x and SAE J2602, four 16-bit PWM modules, two relay drivers, and eight multi-purpose I/Os. Operating voltage ranges from 5.5V to 18V, with functionality down to 3.9V. It supports full-duplex SPI and includes protection against load dump and brown-out conditions.

Feature Summary

• Integrated MLX16x8 16-bit RISC CPU with co-processor for fast multiplication/division

• Memory configuration: 32 kB Flash, 2 kB RAM, and 380 B EEPROM with ECC
• Four 16-bit PWM modules and two integrated relay drivers with free-wheel function

Applications

• Window lifters
• Sun roof actuators
• DC oil, water, and fuel pumps
• Throttle valves
• Automatic head lean systems

Procurement Notes

Verify the ordering suffix 'RE' corresponds to reel packaging as specified in the datasheet. Confirm the temperature range code 'L' indicates -40°C to 150°C operation. Ensure compatibility with QFN32 5x5 package requirements during assembly. Check for any specific firmware version or silicon revision indicated by the final characters if required for your application.

Selection Notes

Select this component for high-current DC and 1/2 phase BLDC motor control where LIN communication is required. Consider the extended temperature range (-40°C to 150°C) for demanding automotive environments. Evaluate the need for external bypass transistors if operating at temperatures above 105°C to manage power dissipation. Verify that the 32 kB Flash and 380 B EEPROM sizes meet your software storage needs.

Part Context

This part belongs to the MLX81150 family of LIN slaves specifically engineered for relay and DC motor control. It serves as a monolithic solution combining MCU, LIN transceiver, and driver capabilities. The LLW-DAA-000-RE variant specifies the QFN32 package, standard options, and reel delivery format.

Replacement Considerations

Consult Melexis for qualified replacement parts. The datasheet references MLX81150D as a related marking/order code variant but does not explicitly list direct cross-references for the RE suffix.
