MA735

MA735

9-Bit to 13-Bit, Digital, Contactless Angle Sensor with ABZ and PWM Outputs in an Ultra-Small UTQFN-14 Package

Datasheet

Description

The MA735 detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Its ultra-small UTQFN package makes it an ideal solution for space-constrained applications. Fast data acquisition and processing provide accurate angle measurements at speeds between 0rpm and 60,000rpm. The digital filtering is adjustable to optimize control loop performance when used in servo applications.

The MA735 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 MA735 features magnetic field strength detection with configurable thresholds to allow sensing of the magnet position relative to the sensor for the creation of functions, such as sensing axial movements or diagnostics.

The on-chip, non-volatile memory (NVM) provides storage for configuration parameters, including the reference zero-angle position, ABZ encoder settings, and magnetic field detection thresholds.

The MA735 is available in a UTQFN-14 (2mmx2mm) package.

TBMA735-Q-LT-00A Long Evaluation Board for the MA735

The TBMA735-Q-LT-00A is the long evaluation board for the MA735 MagAlpha magnetic position sensor. The sensor is mounted on the edge of the board, and can therefore be used in both side-shaft and end-of-shaft configurations.

The TBMA735-Q-LT-00A test board is compatible with the MACOM evaluation kit and EVKT-MagAlpha-MagDiff, offering seamless connection and operation of the MA735 MagAlpha magnetic position sensor.

In addition, the TBMA735-Q-LT-00A allows users to evaluate MagAlpha functionalities and performances with their own set-up.

The TBMA735-Q-LT-00A test board only includes the assembled board with the sensor and decoupling capacitors and connectors. It does not include connectors for certain board types.
