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 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 electronic
components.
Wide operating voltage range of 3.4 Vdc to 24 Vdc
increases application flexibility.
Tested to moisture sensitivity similar to JEDEC J-STD-
020B, MSL Level 1, allowing the VF526DT to be used in
environments where humidity may be a problem.
RoHS-compliant materials meet Directive 2002/95/EC.
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.
