MA780
DESCRIPTION
The MA780 is a low-power angle sensor that detects the absolute angular position of a permanent magnet, such as a diametrically magnetized cylinder on a rotating shaft. With its power-cycling ability, the sensor is optimized for applications that require low average power. Timing can be controlled via an on-chip clock or external controller. Flags are provided to detect 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 that affects the output resolution.
The MA780 is available in a QFN-16 (3mmx3mm) package.
