Product Description
Product Overview
The TLE4905L, TLE4935L, TLE4945L, and TLE4945-2L are digital Hall IC switches designed for magnetic field applications in automotive and industrial sectors. These components offer a digital output signal, compatibility with unipolar and alternating magnetic fields, and a wide operating temperature range with temperature-compensated magnetic performance. They feature integrated reverse polarity protection and output protection against electrical disturbances, making them suitable for position/proximity indicators, brushless DC motor commutation, and rotational indexing.
