TLE4997E2

Description:

The linear Hall IC TLE4997has been designed specifically to meet the demands of highly accurate rotation and position detection, as well as for current measurement applications. 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 and digital temperature compensation guarantees excellent stability over a long period of time. The minimum overall resolution is 12 bits. Nevertheless, some internal stages work with resolutions up to 20 bits.

Summary of Features:

  • High linear and ratiometric push-pull rail-to-rail output signal
  • 20-bit Digital Signal Processing
  • Digital temperature compensation
  • 12-bit overall resolution
  • Operates from -40°C up to 150°C
  • Low drift of output signal over temperature and lifetime
  • Programmable parameters stored in EEPROM with single bit error correction:magnetic range and magnetic sensitivity (gain), zero field voltage (offset) ,bandwidth ,polarity of the output slope ,clamping option ,temperature coefficient for all common magnets ,memory lock Re-programmable until memory lock
  • Single supply voltage 4.5 - 5.5 V (4 - 7 V in extended range)
  • Operation between -200 mT and +200 mT within three ranges
  • Slim 3-pin package (Green)
  • Reverse polarity and overvoltage protection for all pins
  • Output short circuit protection
  • On-board diagnostics (wire breakage detection, undervoltage, overvoltage)
  • Digital readout of internal temperature and magnetic field values in calibration mode.
  • Individual programming and operation of multiple sensors with common power supply
  • Two-point calibration of magnetic transfer function
  • Precise calibration without iteration steps
  • High immunity against mechanical stress, EMC, ESD

Target Applications:

  • Robust replacement of potentiometers ,no mechanical abrasion,resistant to humidity, temperature, pollution and vibration
  • Linear and angular position sensing in automotive applications like pedal position, suspension control, valve or throttle position, headlight levelling and steering angle
  • High current sensing for battery management, motor control, and electronic fuse
