Product Overview
The TLE4905L, TLE4935L, TLE4945L, and TLE4945-2L are digital Hall IC switches designed for magnetic field applications. These components offer a digital output signal suitable for both unipolar and alternating magnetic fields, featuring a wide temperature range and temperature-compensated magnetic performance. They include on-chip protection against reversed polarity and output protection against electrical disturbances. Typical applications include position/proximity indicators, brushless DC motor commutation, and rotational indexing in automotive and industrial environments.
