1. Introduction
The HAL1xy Hall switch family is produced in CMOS
technology. The sensors include a temperature-compensated 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 transistor is switched on or off.
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 HAL1xy family is available in the SMD-package
SOT89B-3 and in the leaded version TO92UA-6.
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.

1.3. Operating Junction Temperature Range
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature TJ).
I: TJ = −20 °C to +125 °C
C: TJ = 0 °C to +85 °C
During soldering reflow processing and manual
reworking, a component body temperature of 260 °C
should not be exceeded.
Welding
Device terminals shall be compatible with laser and
electrical welding. Please, note that the success of the
welding process is subject to different welding parameters 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 component.

2.3. Absolute Maximum Ratings
Stresses beyond those listed in the “Absolute Maximum Ratings” may cause permanent damage to the device. This
is a stress rating only. Functional operation of the device at these conditions is not implied. Exposure to absolute
maximum rating conditions for extended periods will affect device reliability.
This device contains circuitry to protect the inputs and outputs against damage due to high static voltages or electric
fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than absolute maximum-rated voltages to this high-impedance circuit.
All voltages listed are referenced to ground (GND).

3. Application Notes
3.3. Start-up Behavior
3.1. Ambient Temperature
Due to the active offset compensation, the sensors
have an initialization time (enable time ten(O)) after
applying the supply voltage. The parameter ten(O) is
specified in Section 2.5.: Characteristics on page 9.
Due to the internal power dissipation, the temperature
on the silicon chip (junction temperature TJ) is higher
than the temperature outside the package (ambient
temperature TA).
T J = T A + ΔT
At static conditions and continuous operation, the following equation applies:
ΔT = I DD × V DD × R th
During the initialization time, the output state is not
defined and the output can toggle. After ten(O), the output will be low if the applied magnetic field B is above
BON. The output will be high if B is below BOFF.
For magnetic fields between BOFF and BON, the output
state of the HAL sensor after applying VDD will be
either low or high. In order to achieve a well-defined
output state, the applied magnetic field must be above
BONmax, respectively, below BOFFmin.
3.4. EMC and ESD
If IOUT > IDD, please contact Micronas application support for detailed instructions on calculating ambient
temperature.
For applications with disturbances on the supply line or
radiated disturbances, a series resistor and a capacitor
are recommended (see Fig. 3–1). The series resistor
and the capacitor should be placed as closely as
possible to the HAL sensor.
For typical values, use the typical parameters. For
worst case calculation, use the max. parameters for
IDD and Rth, and the max. value for VDD from the
application.
Please contact Micronas for the detailed investigation
reports with the EMC and ESD results.
For all sensors, the junction temperature range TJ is
specified. The maximum ambient temperature TAmax
can be calculated as:

All sensors fulfill the electrical and magnetic characteristics when operated within the Recommended Operating Conditions (see page 8).

Supply Voltage Below 3.8 V
Typically, the sensors operate with supply voltages
above 3 V, however, below 3.8 V some characteristics
may be outside the specification.
Note: The functionality of the sensor below 3.8 V is
not tested. For special test conditions, please
contact Micronas.
