MAQ473GQE-AEC1-P Monolithic Power Systems

MAQ473 9-Bit to 14-Bit, MagAlpha Automotive Angle Sensor with ABZ Incremental and PWM Outputs DESCRIPTION FEATURES The MAQ473 detects the absolute angular 9-Bit to 14-Bit Resolution Absolute Angle position of a permanent magnet, typically a Encoder diametrically magnetized cylinder on a rotating Contactless Sensing for Long Lifespan shaft. Fast data acquisition and processing SPI Serial Interface with Parity Bit for Angle provide accurate angle measurement at speeds Readout and Chip Configuration from 0rpm to 60,000rpm. Configuration Programmable Magnetic Field Strength Detection for Diagnostic Checks The MAQ473 supports a wide range of Incremental 12-Bit ABZ Quadrature magnetic field strengths and spatial Encoder Interface with Programmable configurations. Both end-of-shaft and off-axis Pulses Per Turn from 1 to 1024 (side-shaft mounting) configurations are 14-Bit PWM Output supported. 3.3V, 12mA Supply Current The MAQ473 features magnetic field strength -40C to +150C Operating Temperature detection with programmable thresholds to Available in a QFN-16 (3mmx3mm) allow sensing of the magnet position relative to Package with Wettable Flanks the sensor for creation of functions such as the Available in AEC-Q100 Grade 1 sensing of axial movements or for diagnostics. The on-chip non-volatile memory provides APPLICATIONS storage for configuration parameters, including Automotive the reference zero-angle position, ABZ encoder Angle Encoders settings, and magnetic field detection Automotive Angle or Speed Sensors thresholds. Robotics The MAQ473 is AEC-Q100 qualified, and is All MPS parts are lead-free, halogen-free, and adhere to the RoHS available in a QFN-16 (3mmx3mm) package. directive.
