ams AS5403E
The AS5403 can measure magnetic fields components in all three dimensions and converts the magnetic field information into absolute position information. 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.| Part No. | AS5403E |

GENERAL DESCRIPTION
AS5403A/D/E 3D Hall Position Sensor for Linear and Off-AxisAPPLICATIONS
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. 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.
