MagAlpha MA120 Angular Sensor for Brushless Motor Commutation DESCRIPTION FEATURES The MagAlpha MA120 magnetic sensor is an all- UVW Signals for Block Commutation in-one solution designed to replace Hall switches 11-Bit Resolution Absolute Angle Encoder for 3-phase block commutation in brushless DC 500kHz Refresh Rate motors. The MA120 detects the absolute angular Ultra-Low Latency: 3s position of a permanent magnet, typically a SPI Serial Interface diametrically magnetized cylinder attached to the 3.3V, 7.7mA Supply rotor. The data acquisition and processing is Available in a QFN-16 (3mmx3mm) Package extremely fast, allowing for accurate angle measurement at speeds from 0 to 120,000 RPM. APPLICATIONS The MA120 supports a wide magnetic field PSM/BLDC Motors strength range, which helps relax mechanical All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
