TLE4997E2XALA1

TLE4997E2XALA1 is a programmable linear hall sensor 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 analogue output voltage, which is ideally suited to analogue-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. Targeted applications such as robust replacement of potentiometers: no mechanical abrasion, resistant to humidity, temperature, pollution and vibration, linear and angular position sensing in automotive like pedal position, suspension control.

• High linear and ratiometric push-pull rail-to-rail output signal
• 12-bit overall resolution, two-point calibration of magnetic transfer function
• Low drift of output signal over temperature and lifetime
• Programmable parameters stored in EEPROM with single-bit error correction: bandwidth, memory lock
• Single supply voltage range from 4.5 to 5.5V (4 - 7V in extended range)
• 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
• 3 pin SSO package, temperature range from -40 up to 150°C
