MA600A

The MA600A is a precision, high-bandwidth magnetic angle sensor that detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. With an integrated precision tunnel magnetoresistance (TMR) sensor, the MA600A achieves high bandwidth and high accuracy (INL), making it an ideal solution for position control and robotics.

The MA600A supports a wide range of magnetic field strengths and mounting configurations: end-of-shaft (on-axis) and side-shaft (off-axis).

On-chip non-volatile memory (NVM) provides storage for configuration parameters, including the reference zero-angle position, ABZ, UVW, and pulse-width modulation (PWM) settings.

The MA600A is factory-calibrated to achieve an error (INL) below 0.6° across its operating temperature range. Furthermore, a final system calibration is available through a 32-point, user-configurable correction table. The resulting error (INL) after user calibration can be smaller than 0.1°.

Communication with the MA600A can be accomplished via the serial peripheral interface (SPI) and synchronous serial interface (SSI).

The MA600A supports a daisy-chain configuration. It allows for the sequential SPI angle readout of multiple sensors, which minimizes the number of I/O pins used by the controller device.

The MA600A is available in a small QFN-16 (3mmx3mm) package.
