High Precision Automotive Bipolar Hall Latch
Product Overview
The TLE4961-1M is a high-precision bipolar 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, and operates effectively from 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 robust design and high stability make it ideal for index counting applications, such as power closing and window lifters, especially when used with a pole wheel.
