HAL114
Unipolar Hall Switch IC
in CMOS technology
Introduction
The HAL114 is a Hall switch produced in CMOS technol-
ogy. The sensor includes a temperature-compensated
Hall plate, a Schmitt trigger, and an open-drain output
transistor (see Fig. 2).
The HAL114 has a unipolar behavior: The output turns
low with a magnetic south pole on the branded side of
the package (see figures 3 and 4). The output turns high
if the magnetic field is removed. The output signal re-
mains high if the magnetic north pole approaches the
branded side of the package.
The sensor is designed for industrial and automotive ap-
plications and operates with supply voltages from 4.5 V
to 24 V in the ambient temperature range from –40°C up
to 150 °C.
The HAL114 is available in a SMD-package (SOT-89A)
and in a leaded version (TO-92UA).
Features:
– operates from 4.5 V to 24 V supply voltage
– overvoltage protection
– reverse-voltage protection at VDD-pin
– short-circuit protected open-drain output by thermal
shutdown
– operates with magnetic fields from DC to 20 kHz
– stable magnetic switching points over a wide supply
voltage range
– the decrease of magnetic flux density caused by rising
temperature in the sensor system is compensated by
a built-in negative temperature coefficient of the mag-
netic switching points
– ideal sensor for contactless switches and speed mea-
surement in hostile automotive and industrial environ-
ments
Specifications
– switching type: unipolar
– output turns low with magnetic south pole on branded
side of package
– output turns high if magnetic field is removed

HAL114
Functional Description
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
voltage peaks at the Output-Pin and VDD-Pin together
with external series resistors. Reverse current is limited
at the VDD-Pin by an internal series resistor up to –15 V.
No external reverse protection diode is needed at the
VDD-Pin for values ranging from 0 V to –15 V.
