The MLX81200 is a highly integrated 3 phase motor controller for 12V automotive applications. It includes a 16-Bit-Flash- Micro-controller with a high voltage analog periphery for BLDC motor driving in a very small package. Therefore the MLX81200 enables the industry's smallest control electronics - opening a new dimension in system integration. Its TruSense technology enables sensorless motor driving for a wide range of applications requesting an "on demand" control.

The Melexis TruSense technology combines reluctance measurements with BEMF (Back Electro-Motive Force) sensing, yielding highly accurate rotor position information, in a very wide dynamic range and under heavily changing loads. Because of that, also very demanding applications operating under unknown torque as transmission oil pumps, can be controlled in a sensorless way. The PWM driving scheme might be adapted to any motor current shape, achieving the best possible efficiency, low torque ripple and minimal conducted and radiated emissions.
