AS5045
12 Bit Programmable Magnetic Rotary Encoder
Data Sheet
1 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.
To measure the angle, only a simple two-pole magnet,
rotating over the center of the chip, is required. The
magnet may be placed above or below the IC.
The absolute angle measurement provides instant
indication of the magnet’s angular position with a
resolution of 0.0879° = 4096 positions per revolution.
This digital data is available as a serial bit stream and
as a PWM signal.
An internal voltage regulator allows the AS5045 to
operate at either 3.3 V or 5 V supplies.
2 Benefits
Complete system-on-chip
Flexible system solution provides absolute and
PWM outputs simultaneously
Ideal for applications in harsh environments due to
contactless position sensing
No calibration required
3 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)
4 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
