Magnetic Sensing Device Infineon TLE4961-1M Automotive Hall Effect Latch for Accurate Index Counting
TLE4961-1M High Precision Automotive Hall Effect Latch
Published by Infineon Technologies AG
Product Overview
The TLE4961-1M is a high-precision Hall effect latch designed for automotive and industrial applications requiring accurate magnetic sensing. It features a wide operating supply voltage range from 3.0 V to 32 V with overvoltage capability up to 42 V without an external resistor, making it suitable for demanding environments. The device offers superior temperature stability of magnetic thresholds, low jitter, and high ESD performance. Its magnetic latching behavior and switching thresholds make it ideal for index counting applications, such as power closing and window lifters, operating reliably within a temperature range of -40C to 170C.
