Infineon TLV4976-2K: Value Optimized Hall Effect Switch with Current Interface
Product Overview
The TLV4976-2K is a high-precision unipolar Hall effect switch designed for industrial and consumer applications. It features a two-wire, 6mA/14mA current interface, offering a cost-effective and reliable solution for position sensing. The device utilizes a chopped measurement principle for high stability switching thresholds across a wide operating temperature range of -40C to 85C. Its key advantages include high sensitivity, superior temperature stability, and high resistance to mechanical stress through active error compensation. The current interface minimizes the number of wires required, enhancing reliability, especially in applications where the microcontroller is located at a distance from the Hall switch.
