unipolar Hall effect switch Infineon TLE49641MXTSA1 with output overcurrent and overtemperature protection
TLE4964-1M High Precision Automotive Hall Effect Switch
Product Overview
The TLE4964-1M is a high-precision Hall effect switch designed for demanding automotive and industrial applications. It offers superior supply voltage capability (3.0 V to 32 V with overvoltage protection up to 42 V), a wide operating temperature range (-40C to 170C), and stable magnetic thresholds. Its unipolar switching characteristic with a typical operating point of 18 mT and hysteresis of 5.5 mT makes it ideal for various position detection tasks. Key features include reverse polarity protection, output overcurrent and overtemperature protection, active error compensation for high accuracy, and low jitter for reliable performance.
