1xy
Low-Cost Hall-Effect Sensor Family
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.

Magnetic characteristics are robust
against mechanical stress effects
Short-circuit protected open-drain out-
put by thermal shut down
Constant switching points over a wide
supply voltage and temperature range
The decrease of magnetic flux density
caused by rising temperature in the sen-
sor system is compensated by a built-in
negative temperature coefficient of the
magnetic characteristics
