The TLE4946-2K is a high-precision Hall effect latch designed for demanding applications requiring accurate magnetic switching thresholds up to 150C. It features a wide supply voltage range (2.7V to 24V), operation from unregulated power supplies, and superior temperature stability. Its active error compensation and chopper techniques ensure high accuracy and resistance to mechanical stress. The device offers a digital output signal with 20mA current sink capability and high ESD performance, making it ideal for BLDC motor commutation and other position sensing applications.
