TLE4998P3XALA1

TLE4998P3XALA1 is a programmable linear hall sensor designed specifically to meet the requirements of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a digital PWM signal, which is ideally suited for direct decoding by any unit measuring a duty cycle of a rectangular signal (usually a timer/capture unit in a MCU). Furthermore, it is possible to attach an external lowpass filter, which allows an A/D conversion using sensor supply voltage as a reference. IC is produced in BiCMOS technology with high voltage capability, also providing reverse polarity protection. Digital signal processing, using a 16-bit DSP architecture together with digital temperature compensation, guarantees excellent long-time stability as compared to analogue compensation methods. While the overall resolution is 16-bits, some internal stages work with resolutions up to 20-bits. Targeted applications such as robust replacement of potentiometers.

• PWM open-drain output signal
• Low drift of output signal over temperature and lifetime
• Programmable parameters stored in EEPROM with single bit error correction: PWM output frequency
• Re-programmable until memory lock
• Single supply voltage range from 4.5 to 5.5V (4.1 to 16V in extended range)
• Reverse-polarity and overvoltage protection for all pins, output short-circuit protection
• On-board diagnostics (overvoltage, EEPROM error)
• Digital readout of the magnetic field and internal temperature in calibration mode
• Programming and operation of multiple sensors with common power supply
• 3 pin SSO package, temperature range from -40 up to 125°C
