HAL 5xy
Hall Effect Sensor Family
in CMOS technology
Release Note: Revision bars indicate significant
changes to the previous edition.
1. Introduction
The HAL 5xy family consists of different Hall switches
produced in CMOS technology. All sensors include a
temperature-compensated Hall plate with active offset
compensation, a comparator, and an open-drain out-
put transistor. The comparator compares the actual
magnetic flux through the Hall plate (Hall voltage) with
the fixed reference values (switching points). Accord-
ingly, the output transistor is switched on or off.
The sensors of this family differ in the switching behav-
ior and the switching points.
The active offset compensation leads to constant mag-
netic characteristics over supply voltage and tempera-
ture range. In addition, the magnetic parameters are
robust against mechanical stress effects.
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 150
°C.
All sensors are available in the SMD-package
SOT89B-1 and in the leaded versions TO92UA-1 and
TO92UA-2.

The types differ according to the magnetic flux density
values for the magnetic switching points and the tem-
perature behavior of the magnetic switching points,
and the mode of switching.

1.1. Features:
– switching offset compensation at typically 62 kHz
– operates from 3.8 V to 24 V supply voltage
– overvoltage protection at all pins
– reverse-voltage protection at V
DD
-pin
– magnetic characteristics are robust regarding
mechanical stress effects
– short-circuit protected open-drain output by thermal
shut down
– operates with static magnetic fields and dynamic
magnetic fields up to 10 kHz
– constant switching points over a wide supply volt-
age range
– the decrease of magnetic flux density caused by ris-
ing temperature in the sensor system is compen-
sated by a built-in negative temperature coefficient
of the magnetic characteristics
– ideal sensor for applications in extreme automotive
and industrial environments
– EMC corresponding to ISO 7637

Latching Sensors:
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 out-
put does not change if the magnetic field is removed.
For changing the output state, the opposite magnetic
field polarity must be applied.
Bipolar Switching Sensors:
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 out-
put state is not defined for all sensors if the magnetic
field is removed again. Some sensors will change the
output state and some sensors will not.

1.4. Operating Junction Temperature Range
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature T
J
).
A:
T
J
=
−40 °C
to +170
°C
K:
T
J
=
−40 °C
to +140
°C
Note:
Due to the high power dissipation at high current
consumption, there is a difference between the
ambient temperature (T
A
) and junction tempera-
ture. Please refer to Section 5.1. on page 46 for
details.
Unipolar Switching 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.
Unipolar Switching Sensors with Inverted Output:
The output turns high with the magnetic south 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 north pole on the branded
side.
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.
