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.

General Description

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

10ꢀ.

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.

Ordering Information and Content Guide appear at end of

datasheet.
