Linear Hall sensor Infineon TLE4997E2 with digital temperature compensation and selectable magnetic field ranges

Product Overview

The TLE4997E2 is a programmable linear Hall sensor offering a high linear and ratiometric push-pull rail-to-rail output signal. It features 20-bit Digital Signal Processing, digital temperature compensation, and 12-bit overall resolution. Designed for operation between -40C and 150C, it provides low drift of the output signal over temperature and lifetime. Key programmable parameters stored in EEPROM include magnetic range, sensitivity (gain), zero field voltage (offset), bandwidth, output slope polarity, clamping option, temperature coefficient for common magnets, and memory lock. The device is re-programmable until memory lock and operates from a single supply voltage of 4.5 - 5.5 V (4 - 7 V in extended range). It supports magnetic field ranges from -200 mT to +200 mT across three selectable ranges. The sensor includes built-in protection features such as reverse polarity and overvoltage protection for all pins, output short circuit protection, and on-board diagnostics for wire breakage detection, undervoltage, and overvoltage. It also offers digital readout of internal temperature and magnetic field values in calibration mode.
