General Description  
The AS5045 is a contactless magnetic rotary encoder for  
accurate angular measurement over a full turn of 360°.  
-
Two digital 12bit absolute outputs:  
- Serial interface and  
It is  
a system-on-chip, combining integrated Hall  
elements, analog front end and digital signal processing  
in a single device.  
- Pulse width modulated (PWM) output  
-
-
User programmable zero position  
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.  
Failure detection mode for magnet placement  
monitoring and loss of power supply  
The absolute angle measurement provides instant  
-
-
-
“red-yellow-green” indicators display placement of  
magnet in Z-axis  
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.  
Serial read-out of multiple interconnected AS5045  
devices using Daisy Chain mode  
Tolerant to magnet misalignment and airgap  
variations  
An internal voltage regulator allows the AS5045 to  
operate at either 3.3 V or 5 V supplies  
-
-
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

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
