Accurate bipolar Hall latch Infineon TLV4961-1TB with overcurrent and overtemperature protection features
Product Overview
The TLV4961-1T is a high-precision bipolar Hall effect latch designed for consumer applications requiring superior supply voltage capability and stable magnetic thresholds. It operates from an unregulated power supply ranging from 3.0 V to 26 V and features active error compensation for high accuracy and temperature stability. The device includes output overcurrent and overtemperature protection, high ESD performance, and is available in leaded, halogen-free TO92S packages. Its magnetic latching behavior and precise switching thresholds make it ideal for index counting, rotor position detection in brushless DC motors, and open/closing detection in white goods.
