Target Applications
Target applications for the TLE496x Hall switch family are all applications which require a high precision Hall
switch with an operating temperature range from -40°C to 170°C. Its superior supply voltage range from 3.0 V to
32 V with overvoltage capability (e.g. load-dump) up to 42 V without external resistor makes it ideally suited for
automotive and industrial applications.
The TLE4968-1M has very low magnetic thresholds and a bipolar switching behavior. It is therefore especially
suited for applications which require a high sensitivity device and an output switching close to zero magnetic field
values. Possible applications are BLDC rotor position measurement or speed and position measurements in
camshaft or transmission applications.
