PRODUCT INFORMATION

HAL 2xy

Low-Cost Hall-Effect Sensor Family

PRODUCT INFORMATION

The HAL 2xy Hall switch family is produced

in CMOS technology. The sensors include a

temperature-compensated Hall plate with

active offset compensation, a comparator,

and an open-drain output transistor.

The comparator compares the actual mag-

netic flux through the Hall plate (Hall volt-

age) with the fixed reference values (switch-

ing

points).

Accordingly,

the

output

transistor is switched on or off.

The active offset compensation leads to

magnetic parameters which are robust

against mechanical stress effects. In addi-

tion, the magnetic characteristics are con-

stant in the full supply voltage and tempera-

ture range.

The sensors are designed for industrial and

automotive applications and operate with

supply voltages from 3.8 V to 24 V in the

ambient temperature range from

−40 °C up

to 125

°C.

The HAL 2xy family is available in the

SOT89B SMD package and in the leaded

TO92UA package.
