Buffered Sine and Cosine signals Based on an integrated Hall element array, the angular position of a SSI Interface simple two-pole magnet is translated into analog output voltages. The angle information is provided by means of buffered sine and Low power mode cosine voltages. This approach gives maximum flexibility in system Two programmable output modes: Differential or Single ended design, as it can be directly integrated into existing architectures and optimized for various applications in terms of speed and accuracy. Wide magnetic field input range: 20 80 mT With two independent dies in one package, the device offers true Wide temperature range: -40C to +150C redundancy. Usually the bottom die, which is exposed to slightly less Fully automotive qualified to AEC-Q100, grade 0 magnetic field is employed for plausibility check. Thin punched 32-pin QFN (7x7mm) package 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 3 Applications mechanical constraints and magnetic field. The AS5215 is ideal for Electronic Power Steering systems and general purpose for automotive or industrial applications in microcontroller-based systems. Figure 1.
