Product Brief AS5215 Programmable 360 Magnetic Angle Encoder with Buffered SINE & COSINE Output Signals 1 General Description 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 range of -40C...+150C. 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 cosine 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. 2 Key Features Contactless angular position encoding High precision analog output Buffered Sine and Cosine signals SSI Interface Low power mode Two programmable output modes: Differential or Single ended Wide magnetic field input range: 20 - 80 mT With two independent dies in one package, the device offers true redundancy. Usually the bottom die, which is exposed to slightly less magnetic field is employed for plausibility check. Wide temperature range: -40C to +150C An SSI Interface is implemented for signal path configuration as well as a one time programmable register block (OTP), which allows the customer to adjust the signal path gain to adjust for different mechanical constraints and magnetic field. Thin punched 32-pin QFN (7x7mm) package Fully automotive qualified to AEC-Q100, grade 0 3 Applications The AS5215 is ideal for Electronic Power Steering systems and general purpose for automotive or industrial applications in microcontroller-based systems.
