MLX90380 - Triaxis Resolver Datasheet 1. Features and Benefits 2. Application Examples Triaxis Hall Technology Absolute Rotary Position Sensor Sine and Cosine Analog Outputs Brushless Motor Control Output Refresh Rate 4s Permanent Magnet Synchronous Motor 3.3V and 5V Operating Supply Voltage Brushless DC Motor (BLDC) Operating Temperature Range from -40C to Field-oriented Motor Control 150C Selectable Magnetic Field Axis (X/Y - X/Z - Z/Y) 3. Description Selectable Sensitivity Range (10mT 70mT) The MLX90380 is a monolithic contactless sensor IC End-of-Shaft / Through-Shaft Operation sensitive to the flux density applied orthogonally and parallel to the IC surface. Ratiometric Outputs Programming Through the Connector High-speed dual analog outputs allow the MLX90380 to deliver accurate sine/cosine signals when used with a RoHS Compliant Packages: rotating permanent magnet. Single Die SOIC-8 With a wide range of operating temperature, supply Dual Die Fully Redundant TSSOP-16 voltage and magnetic flux density, the MLX90380 can resolve the angular position of a rotating axis over 360 degrees in many industrial and automotive applications. Selectable magnetic axes ensure compatibility with end-of-shaft and through-shaft configurations. SOIC-8 TSSOP-16 Sensitivity and filter bandwidth can be programmed through the 4 application pins to optimally use the ADC input range of the companion MCU.
