HallLinear Analog Single Sensor Description

The linear Hall IC TLE4997A8 has been specifically designed for highly accurate angle and position detection. The sensor provides a ratiometric analog output voltage, which is ideally suited to Analog-to-Digital (A/D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity protection. Digital signal processing using a 16-bit DSP architecture together with digital temperature and analog stress compensation guarantees excellent stability over the whole temperature range and life time.

Summary of Features

  • Integration of two individual programmable Linear Hall sensor IC’s with ratiometric analog output signal.
  • 20-bit Digital Signal Processing (DSP)
  • Digital temperature compensation
  • 12-bit overall resolution
  • Operating automotive temperature range -40°C to 125°C
  • Low drift of output signal over temperature and lifetime
  • Programmable parameters stored in EEPROM with single-bit error correction: Magnetic range and sensitivity (gain), polarity of the output slope Offset Bandwidth Clamping levels Temperature compensation coefficients to accomodate most common magnet materials Memory lock
  • Supply voltage 4.5-5.5 V (4-7 V extended range)
  • Configurable magnetic range : ±50mT, ±100mT or ±200mT
  • Reverse-polarity and overvoltage protection for all pins
  • Output short-circuit protection
  • On-board diagnostics (wire breakage detection, EEPROM error, overvoltage)
  • Digital readout of internal temperature and magnetic field values in calibration mode
  • Programming and operation of multiple sensors with common power supply
  • Two-point calibration of magnetic transfer function

Target Applications

  • Robust replacement of potentiometers: No mechanical abrasion, resistant to humidity, temperature, pollution and vibration
  • Linear and angular position sensing in automotive and industrial applications with highest accuracy requirements
  • Suited for ASIL applications such as pedal position, throttle position and steering torque sensing
