Programmable Linear Hall Sensor
for Industrial Use
TLE4997I
1
Overview
1.1
Features
• High linear and ratiometric push-pull rail-to-rail output
signal
• 20-bit Digital Signal Processing
• Digital temperature compensation
• 12-bit overall resolution
• Operates from -40°C up to 120°C
• Low drift of output signal over temperature and lifetime
• Programmable parameters stored in redundant EEPROM (single bit error correction):
– magnetic range and magnetic sensitivity (gain)
– zero field voltage (offset)
– bandwidth
– polarity of the output slope
– clamping option
– temperature coefficient for all common magnets
– memory lock
• Re-programmable until memory lock
• Single supply voltage 4.5 - 5.5 V (4 - 7 V in extended range)
• Continuous measurement ranges between -200 mT and +200 mT
• Slim 3-pin package (Green)
• Reverse polarity and overvoltage protection for all pins
• Output short circuit protection
• On-board diagnostics (wire breakage detection, undervoltage, overvoltage)
• Digital readout of internal temperature and magnetic field values in calibration mode.
• Individual programming and operation of multiple sensors with common power supply
• Two-point calibration of magnetic transfer function
• Precise calibration without iteration steps
• High immunity against mechanical stress, EMC, ESD
