bipolar Hall effect latch Infineon TLE49614MXTMA1 with wide voltage range and overvoltage protection
Product Overview
The TLE4961-4M is a high-precision bipolar Hall effect latch designed for demanding automotive and industrial applications. It offers a wide operating supply voltage range from 3.0 V to 32 V with overvoltage capability up to 42 V without external resistors, making it suitable for unregulated power supplies. Key features include reverse polarity protection, output overcurrent and overtemperature protection, active error compensation for stable magnetic thresholds, and low jitter. Its superior temperature stability and magnetic characteristics make it ideal for index counting applications, such as power closing and window lifters, especially when used with pole wheels. The device is qualified for automotive applications according to AEC-Q100.
