Functional Description
The AS5043 is manufactured in a CMOS standard process and uses a spinning current Hall technology for sensing the
magnetic field distribution across the surface of the chip.
The integrated Hall elements are placed in a circle around the center of the device and deliver a voltage representation of
the magnetic field perpendicular to the surface of the IC.
Through Sigma-Delta Analog / Digital Conversion and Digital Signal-Processing (DSP) algorithms, the AS5043 provides
accurate high-resolution absolute angular position information. For this purpose a Coordinate Rotation Digital Computer
(CORDIC) calculates the angle and the magnitude of the Hall array signals.
The DSP is also used indicate movements of the magnet towards or away from the chip and to indicate, when the
magnetic field is outside of the recommended range (status bits = MagInc, MagDec; hardware pin = MagRngn).
A small low cost diametrically magnetized (two-pole) standard magnet, centered over the chip, is used as the input
device.
The AS5043 senses the orientation of the magnetic field and calculates a 10-bit binary code. This code can be accessed
via a Synchronous Serial Interface (SSI). In addition, the absolute angular representation is converted to an analog
signal, ratiometric to the supply voltage.
The analog output can be configured in many ways, such as 360°/180°/90° or 45° angular range, external or internal DAC
reference voltage, 0-100%*VDD or 10-90% *VDD analog output range, external or internal amplifier gain setting.
The various output modes as well as a user programmable zero position can be programmed in an OTP register. As long
as no programming voltage is applied to pin PROG, the new setting may be overwritten at any time and will be reset to
default when power is cycled. To make the setting permanent, the OTP register must be programmed by applying a
programming voltage.
The AS5043 is tolerant to magnet misalignment and unwanted external magnetic fields due to differential measurement
technique and Hall sensor conditioning circuitry.
It is also tolerant to airgap and temperature variations due to Sin-/Cos- signal evaluation.
