1.1

Summary of Features

• Very linear and ratiometric rail-to-rail output signal with push-pull output

• Temperature compensation

• Low drift of output signal over temperature and lifetime

• Programmable parameters stored in fuse memory:

– magnetic range and magnetic sensitivity (gain)

– zero field voltage (offset)

– clamping option

– temperature coefficient (calibrated and fused during production)

– memory lock

• Working over temperatures from -40 °C up to 150 °C

• Single supply voltage 4.5 - 5.5 V

• Continuous measurement ranges between -200 mT and +200 mT or 0 and 400 mT

• Very slim 4-pin package with only 1mm thickness

• Reverse polarity and overvoltage protection for all pins

• Output short circuit protection

• On-board diagnostics (wire breakage detection)

• Individual programming and operation of multiple sensors with common power supply

• Two point calibration of magnetic transfer function

1.2

Target Applications

• Robust replacement of potentiometers

– No mechanical abrasion

– Resistant to humidity, temperature, pollution, and vibration

• Linear and angular position sensing in automotive applications like pedal position,

suspension control, valve or throttle position, headlight levelling, and steering angle

• High current sensing for battery management, motor control, and electronic fuse
