1. Introduction
1.2. Family Overview
The HAL 2xy Hall switch family is produced in CMOS
technology. The sensors include a temperature-com-
pensated Hall plate with active offset compensation, a
comparator, and an open-drain output transistor. The
comparator compares the actual magnetic flux through
the Hall plate (Hall voltage) with the fixed reference
values (switching points). Accordingly, the output tran-
sistor is switched on or off. In addition the HAL22y
sensors features a power-on and undervoltage reset.
The active offset compensation leads to magnetic
parameters which are robust against mechanical
stress effects. In addition, the magnetic characteristics
are constant in the full supply voltage and temperature
range.
The sensors are designed for industrial and automo-
tive 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.
For HAL22y the minimum
supply voltage is 4.3 V.
The HAL 2xy family is available in the SMD package
SOT89B-3 and in the leaded versions TO92UA-5 and
TO92UA-6.
This sensor family consists of sensors with latching
and unipolar output behavior.

1.1. Features
– switching offset compensation
– operates from 3.8 V to 24 V supply voltage (HAL22y
minimum supply voltage is 4.3 V)
– power-on and undervoltage reset in case of HAL22y
– operates with static magnetic fields and dynamic
magnetic fields up to 10 kHz
– overvoltage protection at all pins
– reverse-voltage protection at V
DD
-pin
– magnetic characteristics are robust against
mechanical stress effects
– short-circuit protected open-drain output by thermal
shut down
– constant switching points over a wide supply volt-
age and temperature range
– the decrease of magnetic flux density caused by
rising temperature in the sensor system is compen-
sated by a built-in negative temperature coefficient

1.4. Operating Junction Temperature Range
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature T
J
).
K:
T
J
=
−40 °C
to +140
°C
Note:
Due to power dissipation, there is a difference
between the ambient temperature (T
A
) and
junction temperature. Please refer to section
4.1. on page 15 for details.
Unipolar Sensors:
The output turns low with the magnetic south pole on
the branded side of the package and turns high if the
magnetic field is removed. The sensor does not
respond to the magnetic north pole on the branded side.
Latching Sensors:
The sensors have a latching behavior and require a
magnetic north and south pole for correct functioning.
The output turns low with the magnetic south pole on
the branded side of the package and turns high with
the magnetic north pole on the branded side. The
output does not change if the magnetic field is
removed. For changing the output state, the opposite
magnetic field polarity must be applied.
Unipolar Switching Sensors with Inverted Output
Sensitive to North Pole:
The output turns high with the magnetic north pole on
the branded side of the package and turns low if the
magnetic field is removed. The sensor does not
respond to the magnetic south pole on the branded-
side.

1.3. Marking Code
All Hall sensors have a marking on the package
surface (branded side). This marking includes the
name of the sensor and the temperature range.

1.5. Solderability and Welding
During soldering reflow processing and manual
reworking, a component body temperature of 260
°C
should not be exceeded.
Device terminals shall be compatible with laser and
electrical welding. Please, note that the success of the
welding process is subject to different welding parame-
ters which will vary according to the welding technique
used. A very close control of the welding parameters is
absolutely necessary in order to reach satisfying
results. Micronas, therefore, does not give any implied
or express warranty as to the ability to weld the com-
ponent.
