Overview
The MLX81150LPF-DAA-000-TR is a LIN slave controller featuring an MLX16x8 16-bit RISC CPU, designed for relay and DC motor control. It integrates a LIN transceiver supporting LIN 2.x and SAE J2602, along with four 16-bit PWM modules and two integrated relay drivers. The device includes 32 kByte Flash with ECC, 2 kByte RAM, and 380 Byte EEPROM. Operating voltage ranges from 5.5V to 18V, with functionality down to 3.9V. It supports ambient temperatures from -40°C to 150°C and features a QFN32 5x5 package.
Feature Summary
- Integrated MLX16x8 16-bit RISC CPU with co-processor for multiplication/division
- LIN interface with integrated transceiver supporting LIN 2.x and SAE J2602
- Four 16-bit PWM modules and two relay drivers with free-wheel function
- Memory: 32 kByte Flash (ECC), 2 kByte RAM, 380 Byte EEPROM (ECC)
Applications
- Window lifters
- Sun roof actuators
- DC oil, water, and fuel pumps
- Throttle valves
- Automatic head lean systems
Procurement Notes
Verify the ordering suffix 'TR' indicates reel delivery as per standard Melexis conventions, though the datasheet explicitly lists 'RE' for Reel. Confirm the specific silicon revision associated with the 'F' character in the order code against the latest manufacturer documentation to ensure compatibility with required firmware versions.
Selection Notes
Select this component for applications requiring high current DC or 1/2 phase BLDC motor control via LIN bus. Ensure the operating voltage stays within 5.5V to 18V for full specification; operation below 6V requires prior startup at >6V. For temperatures above 105°C, an external bypass transistor on the RTG pin is mandatory to manage power dissipation.
Part Context
The MLX81150 is part of Melexis' LIN-Slave family for automotive relay and motor control. It serves as a monolithic solution replacing discrete components by integrating the MCU, LIN transceiver, and power drivers into a single QFN32 package. It supports In-Module-Programming via the LIN pin using a special fast protocol.
Replacement Considerations
MLX81150LLW-DAA-000-SP is a listed alternative in the same family with identical electrical specifications but differs in packaging form factor (Tape & Reel vs. Bulk) and potentially delivery configuration.
