The AS5215 is a redundant, contactless rotary encoder sensor for accurate angular measurement over a full turn of 360° and over an extended ambient temperature of -40°C to +150°C.
Based on an integrated Hall element array the angular position of a simple two-pole magnet is translated into analog output voltages. The angle information is provided by means of buffered sine and consine voltages. This approach gives maximum flexibility in system design, as it can be directly integrated into existing architectures and optimized for various applications in terms of speed and accuracy.
With two independent dies in one package, the AS5215 offers true redundancy. The sensitivity of the device, as well as the output mode (differential or single ended) is programmable to keep highest system flexibilty.
An SSI Interface is implemented for signal path configuration as well as a one time programmable register block (OTP), which allows the customer an adjustment of the signal path gain for different mechanical constraints and magnetic fields.
Typical Applications for the AS5215:
-
Electronic Power Steering
-
Contactless Potentiometer
-
Contactless Rotary Switches
-
General Industrial Applications
The AS5215-HQFT is available in a 32-pin QFN package with a wide temperature range of -40ºC to +150ºC.
