TLE4998S3C 데이터시트 - Infineon Technologies

Features
• Single Edge Nibble Transmission (SENT) open-drain output signal (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:
   – SENT 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 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
• Package with two capacitors: 47nF (VDD to GND) and 4.7nF (OUT to GND)

Target Applications
• Robust replacement of potentiometers
   – No mechanical abrasion
   – Resistant to humidity, temperature, pollution and vibration
• Linear and angular position sensing in automotive applications such as pedal position, suspension control, throttle position, headlight levelling, and steering torque sensing
• Sensing of high current for battery management, motor control, and electronic fuses
