MA780

8-Bit to 12-Bit, Low-Power Angle Sensor with Integrated Wake-Up Angle Detection

Datasheet

Description

The MA780 is an 8-bit to 12-bit, low-power angle sensor that detects the absolute angular position of a permanent magnet (e.g. a diametrically magnetized cylinder on a rotating shaft). Power-cycling optimizes the sensor for applications requiring low average power. The timing can be controlled via an integrated 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.

The 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. The MA780 is available in a QFN-16 (3mmx3mm) package.

Evaluation Tools

TBMA780-Q-LT-01A Evaluation Kit Long Evaluation Board for the MA780

The TBMA780-Q-LT-01A is the long test board for the MA780 MagAlpha magnetic position sensor, the world's smallest absolute ICEncoder^TM. The sensor is mounted on the edge of the board, and can be used in both side-shaft and end-of-shaft configurations.

It requires the EVKT-MACOM communication kit and the Macom App Software to evaluate MagAlpha functionality and performance with the set-up, such as noise level, refresh rate, start-up time, and magnetic field dependence.
