Magnetic Angle Sensoraustriamicrosystems has announced the AS5165, a contactless magnetic angle position sensor for accurate angular measurement over a full 360°. The new high-resolution magnetic rotary sensor offers desirable protection features for reliable operation in harsh automotive environments and includes a SENT J2716 interface for simple transmission of high-resolution sensor information. The AS5165 magnetic encoder is a system-on-chip and combines integrated Hall elements, an analog front-end, and digital signal processing in a single device. Offering the most reliable performance available, the AS5165 provides protection for the power supply and output pins against overvoltage up to 27 V; power supply pins are also protected against reverse polarity to -18 V. In addition, continuous short circuit detection and broken wire detection are provided, and a patented fully differential architecture makes the sensor insensitive to stray magnetic fields. Automotive applications for the AS5165 include throttle and valve position sensing and several power train sensing applications. To measure an 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.
