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

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

– Bandwidth

– Clamping levels

– Customer temperature compensation coefficients for all common magnets

•

Re-programmable until memory lock

•

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

•

Configurable magnetic range: ±50 mT, ±100 mT, or ±200 mT

•

Reverse-polarity and overvoltage protection for all pins

•

Output short-circuit protection

•

On-board diagnostics (overvoltage, EEPROM error)

•

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

Note: Product qualification is based on “AEC Q100 Rev. G” grade 1 (Automotive Electronics Council - Stress test

qualification for integrated circuits)
