1 / 47 page  ams Datasheet Page 1 [v2-01] 2017-Jul-13 Document Feedback AS5045 12-Bit Programmable Magnetic Rotary Position Sensor The AS5045 is a contactless magnetic position sensor for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879° = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. An internal voltage regulator allows the AS5045 to operate at either 3.3 V or 5 V supplies. Ordering Information and Content Guide appear at end of datasheet. Key Benefits & Features The benefits and features of AS5045, 12-Bit Programmable Magnetic Rotary Position Sensor are listed below: Figure 1: Added Value of Using AS5045 • Two digital 12-bit absolute outputs: • Serial interface and • Pulse width modulated (PWM) output • Failure detection mode for magnet placement monitoring and loss of power supply • “Red-Yellow-Green” indicators display placement of magnet in Z-axis Benefits Features • Highest reliability and durability in harsh environments • Contactless absolute angle position measurement • Great flexibility during assembly • User programmable zero position • Operation safety • Diagnostic modes for magnet detection and power supply loss • Lower material cost (no magnetic shielding needed) • Immune to external magnetic stray fields General Description |
