Features

•

Integration of two individual programmable Linear Hall sensor IC’s with PWM open-drain output signal

•

20-bit Digital Signal Processing

•

Digital temperature and stress compensation

•

12-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:

– PWM output frequency

– 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)

•

Digital readout of the magnetic field and internal temperature in calibration mode

•

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)
