The HAL114 is a CMOS integrated circuit with a switch-
ing output in response to magnetic fields. It processes
the “Hall Voltage” internally: The Hall Voltage is propor-
tional to the magnetic flux component Bz orthogonal to
an integrated Hall Plate, in case an electric current is im-
posed to the plate. The HAL114 compares the Hall Volt-
age with a predefined threshold and generates the out-
put signal dependent of the direction of the magnetic
field. A special circuit compensates for the temperature
dependent effects of the IC, as well as the external mag-
net. A built-in hysteresis eliminates possible oscillations
of the output signal adjacent to its switching point so that
“output bouncing” is avoided. The output is short-circuit
protected by limiting high currents and by sensing ex-
cess temperature. Shunt protection devices clamp
