Product Description
High Precision Automotive Hall Effect Latch TLE4961-1L
Product Overview
The TLE4961-1L is a high-precision Hall effect latch designed for demanding automotive and industrial applications. It offers a wide operating supply voltage range (3.0 V to 32 V) with overvoltage capability up to 42 V, 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 latching magnetic behavior and precise switching thresholds (typically 2 mT) make it ideal for index counting applications, such as power closing and window lifters.
