Product Description
Uni- and Bipolar Hall IC Switches for Magnetic Field Applications
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 and are suitable for both unipolar and alternating magnetic fields. They feature a large temperature range, temperature-compensated magnetic performance, and integrated protection against reversed polarity and electrical disturbances. These Hall ICs are ideal for automotive and industrial applications, including position/proximity indicators, brushless DC motor commutation, and rotational indexing.
