Product Description
Product Overview
The TLV4961-1T is a high-precision bipolar Hall effect latch designed for consumer and industrial applications requiring stable magnetic thresholds and superior supply voltage capability. It operates from an unregulated power supply, offering a wide voltage range from 3.0 V to 26 V. Key features include output overcurrent and overtemperature protection, active error compensation for enhanced stability, and high ESD performance. This latch is ideal for index counting, rotor position detection in brushless DC motors, white goods, and open/closing detection applications where precise magnetic sensing is crucial.
