1. Introduction
The HAL1xy 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.
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.

1.4. Solderability and Welding
Soldering
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 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.
