General Description

The AS5045 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.

Key Features

? Contactless high resolution rotational position encoding over a full turn of 360 degrees

? Two digital 12bit absolute outputs:

- Serial interface and

- Pulse width modulated (PWM) output

? User programmable zero position

? Failure detection mode for magnet placement monitoring and loss of power supply

? “red-yellow-green” indicators display placement of magnet in Z-axis

? Serial read-out of multiple interconnected AS5045 devices using Daisy Chain mode

? Tolerant to magnet misalignment and airgap variations

? Wide temperature range: - 40°C to + 125°C

? Small Pb-free package: SSOP 16 (5.3mm x 6.2mm)

Applications

? Industrial applications:

- Contactless rotary position sensing

- Robotics

? Automotive applications:

- Steering wheel position sensing

- Transmission gearbox encoder

- Headlight position control

- Torque sensing

- Valve position sensing

? Replacement of high end potentiometers
