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 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 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

POTENTIAL APPLICATIONS

Transportation

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.

Anti-pinch electric motor control systems for:

power windows

power seats (headrest)

power sliding doors

sunroofs

Magnetic encoding for electronic steering systems

Industrial

Motion control systems for pulleys and belts

Garage door openers and sliding doors

Position and velocity detection in industrial equipment

Linear displacement sensing (using a magnetic strip of

alternating poles)

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.
