PRODUCT INFORMATION

HAL

Low-Cost Hall-Effect Sensor Family

PRODUCT INFORMATION

The HAL 1xy Hall switch family is designed

for home appliances and industrial applica-

tions. The sensors are produced in CMOS

technology and include a temperature-com-

pensated Hall plate with active offset com-

pensation, 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 HAL 1xy family is available in the

SOT89B SMD package and in the leaded

TO92UA package.
