MagAlpha MA782 Ultra-Small, Low-Power Angle Sensor with Integrated Wake Up Angle Detection DESCRIPTION FEATURES The MA782 detects the absolute angular 8-Bit to 12-Bit Resolution Absolute position of a permanent magnet, such as a Contactless Angle Encoder diametrically magnetized cylinder on a rotating <0.5A Current Consumption in Idle Mode shaft. With its power cycling ability, the MA782 10mA Current Consumption in Active Mode can be optimized for applications that require low Angle Detection Interrupt to Wake the average power. The timing can be controlled by System an on-chip clock or via an external controller. Magnetic Field Strength Alarm Flags can detect a definable amount of angle Supports On-Axis and Off-Axis Operation change. Serial Peripheral Interface (SPI) The device supports a wide range of magnetic 3.3V Supply field strengths and spatial configurations. Both -40C to +125C Operating Temperature end-of-shaft and off-axis (side-shaft mounting) Available in a QFN-14 (2mmx2mm) configurations are supported. Package The MA782 features magnetic field strength APPLICATIONS detection with configurable thresholds to sense Portable Devices the magnet position relative to the sensor for Tablet Foldable Displays certain functions (e.g. sensing the axial movements or for diagnostics). Mobile Flip Phones E-Bike Shifters and Throttle Control On-chip non-volatile memory (NVM) stores Smart Door Locks configuration parameters, including the Low-Power Rotary HMI Dials or Push- reference zero angle position, the power cycling Buttons parameters, the filter window affecting the output resolution, and magnetic field detection All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
