Overview
1.1
Features
• PWM open-drain output signal
• 20-bit Digital Signal Processing
• Digital temperature compensation
• 12-bit overall resolution
• Operates within automotive temperature range
• Low drift of output signal over temperature and lifetime
• Programmable parameters stored in EEPROM with
single bit error correction:
PG-SSO-3-10
– PWM output frequency
– Magnetic range and magnetic sensitivity (gain),
polarity of the output slope
– Offset
– Bandwidth
– Clamping levels
– Customer temperature compensation coefficients
– Memory lock
• Re-programmable until memory lock
• Single supply voltage 4.5 - 5.5 V (4.1 - 16 V in
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)
• 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
• High immunity against mechanical stress, EMC, ESD
