Overview
TLE4998C3
TLE4998C4
1.1
Features
• 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 compensation
• 16-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:
– 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
– Memory lock
• Re-programmable until memory lock
• 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, 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
