AS5215

Programmable 360º 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 360º and over an

extended ambient temperature range of -40ºC to +150ºC.

2 Key Features

ꢀ

Contactless angular position encoding

High precision analog output

Buffered Sine and Cosine signals

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.

SSI Interface

Low power mode

Two programmable output modes: Differential or Single ended

Wide magnetic field input range: 20 – 80 mT

Wide temperature range: -40ºC to +150ºC

Fully automotive qualified to AEC-Q100, grade 0

Thin punched 32-pin QFN (7x7mm) package

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.

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.

3 Applications

The AS5215 is ideal for Electronic Power Steering systems and

general purpose for automotive or industrial applications in

microcontroller-based systems.
