TLE4946-2L High Precision Hall Effect Latch About this document Overview The TLE4946-2L is a high precision Hall effect latch with highly accurate switching thresholds for operating temperatures up to 150C. Features 2.7 V to 18 V supply voltage operation. Operation from unregulated power supply. High sensitivity and high stability of the magnetic switching points. High resistance to mechanical stress by active error compensation Reverse battery protection (V = -18 V) S Superior temperature stability Low jitter (typically 1 s) High ESD performance ( 4 kV HBM) Digital output signal Target applications The TLE4946-2L is an integrated circuit Hall-effect sensor with low switching thresholds and low hysteresis. It is specially designed for high sensitivity applications and is ideally suited to detect the rotor position in a BLDC motor. Also for index counting with small pole wheels and large air gaps the sensor provides a reliable switching information.
