Features

•

Integration of two individual Linear Hall sensor IC’s with Single Edge Nibble Transmission (SENT) open-drain

output signal (SAE J2716)

•

20-bit Digital Signal Processing (DSP)

•

Digital temperature and stress compensation

•

16-bit overall resolution

•

Operating automotive temperature range -40°C to 125°C

•

Minimal drift of output signal over temperature and lifetime

•

Programmable parameters stored in EEPROM with single-bit error correction:

– SENT unit time

– Magnetic range and sensitivity (gain), polarity of the output slope

– Offset

– Bandwidth

– Clamping levels

– Customer temperature compensation coefficients for all common magnets

– Memory lock

•

Re-programmable until memory lock

•

Supply voltage 4.5-5.5 V (4.1-16 V extended range)

•

Operation between -200 mT and +200 mT within three ranges

•

Reverse-polarity and overvoltage protection for all pins

•

Output short-circuit protection

•

On-board diagnostics (overvoltage, EEPROM error, start up)

•

Output of internal magnetic field values and temperature

•

Programming and operation of multiple sensors with common power supply

•

Two-point calibration of magnetic transfer function without iteration steps

•

High immunity against mechanical stress, EMC, ESD
