This document describes several Hall-effect integrated circuits (ICs) designed for automotive and industrial applications. The ICs (TLE 4904, TLE 4934, TLE 4944) provide precise switching points and high temperature stability using on-chip compensation. They include protections against overvoltage, reversed polarity, overstress, and short circuits. The ICs are suitable for unipolar and bipolar magnetic field sensing and switch or latch based on exceeding threshold values for magnetic induction.
