Integrated LIN driver is in QFN24 package

Melexis has integrated 48kbyte of memory into its smallest all-in-one LIN driver. The MLX81160 is the latest member of the Gen3 family of compatible embedded motor drivers.

The 48kbyte of memory (16kbyte ROM for the LIN protocol and 32kbyte flash for the application software) makes the MLX81160 suitable for automotive applications such as window lifters and sunroof regulators with relay DC motors, as well as small DC motor applications with external PN-MOSFET power regulation. 

According to Melexis it offers fast programmability (with 32kbyte flash completed in less than 2.5 seconds) and ASIL B functional safety capabilities. A dual current sensing feature permits ripple counting and the driving of multiple DC motors.

The LIN-based pre-driver uses Melexis’ high voltage silicon-on-isolator (SOI) technology and is claimed to exhibit operational robustness for 12 and 24 V applications.

It is AEC-Q100 qualified and incorporates a LIN interface, an embedded microcontroller unit, six PWM drivers and three high-voltage I/Os. Extra I/Os allow the connection of a dedicated four-wire latch for motor indexing. 

The MLX81160 is embedded into a compact 4.0 x 4.0mm QFN24 package for minimal PCB space requirements. 

Melexis designs, develops and delivers micro-electronic solutions, with a portfolio of mixed-signal semiconductor sensors and actuators which integrate sensing, driving and communication into products and systems. 

Melexis claims it is a world leader in automotive sensors. Today, on average, every new car produced worldwide contains 18 Melexis chips, reports the company. Melexis uses this expertise to serve other markets, including alternative mobility, smart appliances, smart buildings, robotics, energy management and digital health. 

Melexis is headquartered in Belgium and has 18 locations worldwide.
