MONOLITHIC POWER SYSTEMS (MPS) MA734GQ-P Datasheet & Stock

MA734 is a MagAlpha digital angle sensor that detects absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Fast data acquisition and processing provide accurate angle measurements from static angle measurement to high-speed rotation. This sensor supports a wide range of magnetic field strengths and spatial configurations. MA734 detects the strength of magnetic field and includes configurable thresholds that can be used for push-button human-machine interface (HMI) applications or for diagnostic purposes. An on-chip, non-volatile memory provides storage for configuration parameters, such as the reference zero-angle and magnetic field detection thresholds. It is also possible to program the MA734 with volatile registers without accessing the NVM. The MA734 is available in QFN-16 (3x3mm) package. Applications include general-purpose angle measurement, high-resolution angle encoders, automotive position sensing and robotics.
