VF526DT

DESCRIPTION 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 VF526DT’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. The miniature, 4-pin SOT-89B package surface mounts on PC (Printed Circuit) boards and flexible circuits. FEATURES AND BENEFITS Temperature-compensated magnetics and ultra-low offset drift with temperature provides a stable output over a full temperature range of -40 °C to 125 °C [-40 °F to 257 °F]. Single, miniature 4-pin SOT-89B plastic package supplied on tape and reel for automated assembly, allowing potential savings in PC board space and labor cost. Two separate built-in Hall sensors and their associated logic circuitry provide a frequency signal for speed output and a logic level (high or low) signal for direction output, potentially replacing multiple sensors and...
