MA734GQ-P

MA734 is a MagAlpha digital angle sensor that detects absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. Fast data acquisition and processing provide accurate angle measurements from static angle measurement to high-speed rotation. This sensor supports a wide range of magnetic field strengths and spatial configurations. MA734 detects the strength of magnetic field and includes configurable thresholds that can be used for push-button human-machine interface (HMI) applications or for diagnostic purposes. An on-chip, non-volatile memory provides storage for configuration parameters, such as the reference zero-angle and magnetic field detection thresholds. It is also possible to program the MA734 with volatile registers without accessing the NVM. The MA734 is available in QFN-16 (3x3mm) package. Applications include general-purpose angle measurement, high-resolution angle encoders, automotive position sensing and robotics.

• 8bit to 12.5bit, 3µs low-latency contactless angle sensor
• 3µs of latency at constant rotation speed
• SPI serial interface for digital angle readout and chip configuration
• Programmable magnetic field strength detection for diagnostic checks
• NVM read/write command extends memory life
• 3.3V, 11mA supply current, 0rpm to 60,000rpm rotation
• Interrupt out when angle change is detected
• Digital filtering is adjustable to optimize control loop performance in servo motor applications
• Both end-of-shaft and side-shaft (off-axis mounting) configurations are supported
