MA780GQ-Z

MagAlpha™ MA780 Low-Power Angle Sensor

Monolithic Power Systems (MPS) MagAlpha™ MA780 Low-Power Angle Sensor is used to detect the absolute angular position of a permanent magnet. For example, a diametrically magnetized cylinder on a rotating shaft. This sensor, with its power-cycling ability, is suitable for applications requiring low average power. The timing can be controlled via an on-chip clock or external controller. Flags are available for detecting a definable amount of angle change. The MA780 supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and off-axis (side-shaft mounting) configurations are supported. On-chip, non-volatile memory (NVM) provides storage for configuration parameters, including the reference zero angle position, power-cycling parameters, and the filter window affecting the output resolution.
