General Description
AS5403A/D/E
3D Hall Position Sensor for Linear and
Off-Axis Applications
The AS5403 can measure magnetic fields components in all
three dimensions and converts the magnetic field information
into absolute position information.
Only a simple 2-pole magnet is required as the magnetic field
source.
Using two 3D-Hall cells allows absolute (single pixel) as well as
differential (double pixel) 3D magnetic field measurement.
The differential measurement makes the AS5403 ideal for use
in rough automotive position sensing applications that include
not only dust, dirt or moisture but also unwanted magnetic
stray fields.
All the signal conditioning, including compensation of
temperature effects as well as linearization of the output is
included in the IC.
The absolute position information of the magnet is directly
accessible over a SPI interface and a programmable PWM or
analog output. The build in diagnostic functions makes the
AS5403 suitable for safety critical applications.
The AS5403 is available in a 14-pin TSSOP package and is
qualified according AEC-Q100 for an ambient temperature
range from -40°C to 150°C. It operates at a supply voltage of 5V
±10%.
The programming of the AS5403 is done over the single wire
UART interface.
The AS5403 is overvoltage protected up to 18V on the supply
and output pins. In addition the supply pins are reverse polarity
protected up to -18V.
