MA736

8-Bit to 12.5-Bit, 3μs Low-Latency, Ultra-Small, Contactless Digital Angle Sensor

Datasheet

Description

The MA736 is a MagAlpha digital angle sensor that 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 from static angle measurement to high-speed rotation. The digital filtering is adjustable to optimize control loop performance when used in servo motor applications.

This sensor supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and side-shaft (off-axis mounting) configurations are supported.

The MA736 detects the strength of the magnetic field, and includes configurable thresholds that can be used for diagnostic purposes. An on-chip, non-volatile memory (NVM) provides storage for configuration parameters, such as the reference zero-angle and magnetic field detection thresholds. It is also possible to configure the MA736 with volatile registers without accessing the NVM.

The MA736 is available in a UTQFN-14 (2mmx2mm) package.
