TLE49681MXTMA1

TLE49681MXTMA1 is a high-precision automotive unipolar hall effect switch. Target applications for the TLE496x hall switch family are all applications that require a high precision hall switch with an operating temperature range from -40°C to 170°C. Its superior supply voltage range from 3.0V to 32V with overvoltage capability (e.g. load-dump) up to 42V without an external resistor makes it ideally suited for automotive and industrial applications. The TLE4968-1M has very low magnetic thresholds and bipolar switching behavior. It is therefore especially suited for applications that 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.
