Melexis introduced the second generation Triaxis motor position sensor

Recently, Melexis, a global microelectronics company, announced the second generation of its position sensor (resolver) based on its patented Triaxis® Hall magnetism sensing technology.


Second generation motor position sensor (resolver) based on its patented Triaxis® Hall magnetosensitive technology.


The new MLX90380 single-chip solution can be used to measure the absolute motor angle for all brushless motors including Permanent Magnet Synchronous Motors (PMSMs) and Brushless DC motors (BLDCs). Automotive electrification has given rise to a growing number of applications , MLX90380 this provides the ideal solution.
The sensor's 2us input signal sample rate and 8us output signal refresh rate make it ideal for high speed rotary motor applications such as automotive electric power steering (EPS) and superchargers; the MLX90380 offers sine and cosine proportional to VDD Analog signal output, support 10mT ~ 70mT magnetic field strength of the work environment, and XYZ three directions of the magnetic field can be configured.
The MLX90380 is unique in that it can be mounted at the end of the shaft or beside the shaft by simply selecting the correct product code and by means of the ring magnet on the rotor shaft and the MLX90380 mounted on the side, Position Measurement of rotor speed and position.
Peter Vandersteegen, product manager for Melexis, commented on the new product MLX90380: 'This Triaxis®-based second-generation resolver (resolver) shows Melexis a significant step forward - particularly in terms of performance And installation flexibility, the compact device offers many options for designers to offer high-performance rotational angle measurement solutions due to the small space challenges designers face in modern applications, particularly in the automotive world.
Operating from -40 ° C to + 150 ° C, the MLX90380 is ideally suited for demanding applications in industrial and automotive applications. The standard version is available in a small SOIC-8 package and the full redundancy version is available in a SOIC-16 package. Such as PCB-less applications installed directly in the motor, which are available in DMP-4 packages.
ISO26262 documentation can be used to support safety-critical automotive applications.
The MLX90380 can be used with Melexis' small driver IC, the MLX81310 or MLX81315, to drive and position the smart valve for efficient cooling of the battery or the engine. It can also be used with Melexis BLDC motor control IC MLX81205 -06-07-08 Used to track the rotor position of an intelligent pump to provide effective dynamic control of the pump with the right torque.
