Product Description
Product Overview
The TLE4961-1K is a high-precision automotive Hall effect latch designed for demanding applications requiring superior supply voltage capability, an extended operating temperature range (-40C to 170C), and stable magnetic thresholds. With a wide operating supply voltage from 3.0 V to 32 V and overvoltage capability up to 42 V without an external resistor, it is ideal for automotive and industrial environments. Its latching magnetic behavior and precise switching thresholds (typical 2 mT) make it well-suited for index counting applications, such as power closing and window lifters, in conjunction with pole wheels.
