Infineon Technologies AG Magnetic position sensors, Linear sensors TLE4998S8

Description
XENSIV(TM) - TLE4998S8 Linear Hall sensor for linear and angular position sensing The linear Hall IC TLE4998S8 has been designed specifically to meet the requirements of highly accurate angle and position detection. The sensor provides a digital SENT signal based on the SAE J2716 standard, which consists of a sequence of pulses. Each transmission consists of multiple data nibbles containing the Hall value, the temperature and status information of the sensor. The output stage is an open-drain driver pulling the output pin to low only. Therefore, the high level needs to be obtained by an external pull-up resistor. This output type has the advantage that the receiver may use an even lower supply voltage (e.g. 3.3 V). In this case the pull-up resistor must be connected to the given receiver supply. Summary of Features Integration of two individual Linear Hall sensor IC’s with Single Edge Nibble Transmission (SENT) open-drain output signal (SAE J2716) 20-bit Digital Signal Processing (DSP) Digital temperature and stress compensation 16-bit overall resolution Operating automotive temperature range -40°C to 125°C Minimal drift of output signal over temperature and lifetime Programmable parameters stored in EEPROM with single-bit error correction: SENT unit time Magnetic range, sensitivity (gain), offset, and polarity of the output slope Filter Bandwidth Clamping levels� Customer temperature compensation coefficients for all common magnets Re-programmable until memory lock Supply voltage 4.5-5.5 V (4.1-16 V extended range) Configurable magnetic range: ±50 mT, ±100 mT, or ±200 mT Reverse-polarity and overvoltage protection for all pins Output short-circuit protection On-board diagnostics (overvoltage, EEPROM error) 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 Potential 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 safety applications such as pedal position, throttle position and steering torque sensing � Applications Electric power steering (EPS)
