MagAlpha MA780 8-Bit to 12-Bit, Low-Power Angle Sensor with Integrated Wake-Up Angle Detection DESCRIPTION FEATURES The MA780 is a low-power angle sensor that 8-Bit to 12-Bit Resolution Absolute detects the absolute angular position of a Contactless Angle Encoder permanent magnet, such as a diametrically <0.5A Current Consumption in Idle Mode magnetized cylinder on a rotating shaft. With its 10mA Current Consumption in Active Mode power-cycling ability, the sensor is optimized for Angle Detection Interrupt to Wake System applications that require low average power. Supports On-Axis and Off-Axis Operation Timing can be controlled via an on-chip clock or Serial Peripheral Interface (SPI) external controller. Flags are provided to detect 3.3V Supply a definable amount of angle change. -40C to +125C Operating Temperature The MA780 supports a wide range of magnetic Available in a QFN-16 (3mmx3mm) field strengths and spatial configurations. Both Package end-of-shaft and off-axis (side-shaft mounting) APPLICATIONS configurations are supported. General-Purpose Angle Measurements On-chip, non-volatile memory (NVM) provides Battery-Powered Devices storage for configuration parameters, including Multi-Turn Encoders the reference zero-angle position, power cycling parameters, and the filter window that affects the Low-Power Rotary Knob Interfaces output resolution. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Quality The MA780 is available in a QFN-16 (3mmx3mm) Assurance.
