LIN dual core embedded in Melexis’ MLX81200 sensorless BLDC controller

December 3, 2009 - Ieper, Belgium. Melexis: The integrated LIN transceiver of the MLX81200 high temperature flash controller has been certified according to LIN1.3, 2.0, 2.1 and SAE-J2602 physical layer specifications. Combined with the certified LIN API’s (application programming interface), the MLX81200 is now able to apply its proven TruSense sensorless technology in the growing field of BLDC applications with a LIN interface, from sine wave controlled HVAC blowers to 200W on-demand water pumps.

The MLX81200 features the Melexis LIN dual core architecture. This dual core allows customers to develop their application code independent from the LIN task. The application software, which runs on the 16bit application MCU, runs independent from the communication task which runs on the other core. Validated application code does not have to be revalidated when switching between the different LIN standards. The Melexis LIN API has been validated on the LIN1.3, 2.0, 2.1 and SAE J2602 Data Link Layers, and is in production on a wide range of other dual core LIN products, including motor controllers, IO extension modules and sensors.

The MLX81200 is available in QFN48 and TQFP48 7*7mm packages. Samples and full development kit are available. More information can be found on our website www.melexis.com.
