Overview
TLE4990
Programmable Linear Hall Sensor
Overview
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
