Product Description
Product Overview
The Infineon TLE4905L, TLE4935L, TLE4945L, and TLE4945-2L are unipolar and bipolar Hall IC switches designed for magnetic field applications. These sensors offer a digital output signal, operate over a large temperature range with temperature-compensated magnetic performance, and include integrated protection against reversed polarity and electrical disturbances. They are suitable for automotive and industrial applications, including position/proximity indicators, brushless DC motor commutation, and rotational indexing.
