VF526DT
Latching dual Hall-effect digital sensor ICs with speed & direction outputs. SOT-89B (pocket tape & reel) package. Dual sink output
The VF526DT Bipolar Latch, Dual Hall-effect Digital Position Sensor has two distinct Hall sensing elements precisely located 1,4 mm [0.055 in] apart on a single integrated circuit chip. The elements are encapsulated in a thermoset molding material.
The two active Hall latches provide speed and direction indication of a magnetic gradient (such as a rotating ring magnet) across the face of the package.
The miniature, 4-pin SOT-89B package surface mounts on PC (Printed Circuit) boards and flexible circuits. The VF526DT̵7:s built-in temperature compensation is designed to match the temperature coefficient of low-cost magnets, allowing for a reliable, yet cost-effective, sensor-magnet combination.
A unique, regulator circuit provides extremely stable operation with supply voltages from 3.4 Vdc to 24 Vdc. It can directly interface with many electronic components without buffering or compensation circuitry.
