1.1 Features
• Integration of two individual programmable Linear Hall sensor IC’s with SPC (Short PWM Code) protocol with
enhanced interface features based on SENT (Single Edge Nibble Transmission, defined by 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:
– SPC protocol modes: synchronous transmission, dynamic range selection, ID selection mode
– SPC 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
