HAL11x
Hall Effect Sensor Family
in CMOS technology
Release Notes: Revision bars indicate significant
changes to the previous edition.
1. Introduction
The HAL 11x family consists of different Hall switches
produced in CMOS technology.
All sensors include a temperature-compensated Hall
plate, 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 sensors of this family
differ in the switching behavior.
The sensors are designed for industrial and automotive
applications and operate with supply voltages from
4.5 V to 24 V in the ambient temperature range from
–40 °C up to 125 °C.
All sensors are available in an SMD-package (SOT-89B)
and in a leaded version (TO-92UA).
1.2. Family Overview
The types differ according to the mode of switching.
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
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.
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.
1.1. Features
– operates from 4.5 V to 24 V supply voltage
– overvoltage protection
– reverse-voltage protection at V
– short-circuit protected open-drain output by thermal
shut down
– operates with static magnetic fields and dynamic mag-
netic fields up to 20 kHz
– stable 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 magnetic characteristics

2. Functional Description
The HAL11x sensors are monolithic integrated circuits
which switch in response to magnetic fields. If a
magnetic field with flux lines perpendicular to the
sensitive area is applied to the sensor, the biased Hall
plate forces a Hall voltage proportional to this field. The
Hall voltage is compared with the actual threshold level
in the comparator. The temperature-dependent bias
increases the supply voltage of the Hall plates and
adjusts the switching points to the decreasing induction
of magnets at higher temperatures. If the magnetic field
exceeds the threshold levels, the open drain output
switches to the appropriate state. The built-in hysteresis
eliminates oscillation and provides switching behavior of
output without bouncing.
Shunt protection devices clamp voltage peaks at the
Output-pin and V
resistors. Reverse current is limited at the V
-pin together with external series
DD
-pin by an
DD
internal series resistor up to –15 V . No external reverse
protection diode is needed at the V
-pin for reverse
DD
voltages ranging from 0 V to –15 V.

The magnetic limits given above refer to parts in the original packaging. Mechanical stress on the hall sensitive areas
on the chip surface may generate an additional magnetic offset, which can slightly change the magnetic switching
points. This behavior is a physical phenomenon and not a malfunction of the sensor. Mechanical stress on the hall plates
can be caused, for example, by overmoulding the plastic package or by wide range temperature changes like soldering
or operating the parts at extreme temperatures.
Please use a sensor of the HAL5xx family if higher robustness against mechanical stress is required.

The HAL1 15 is a bipolar switching sensor (see Fig. 4–5).
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
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.
For correct functioning in the application, the sensor requires both magnetic polarities (north and south) on the
branded side of the package.

– typical B

– operates with static magnetic fields and dynamic mag-

Applications
The HAL 115 is the optimal sensor for all applications
with alternating magnetic signals at the sensor position
such as:
– rotating speed measurement,
– commutation of brushless DC-motors and cooling
fans.

The HAL1 1x sensors can operate without external components. For applications with disturbances on the supply line or radiated disturbances, a series resistor and a
capacitor are recommended (see Fig. 5–1).
The series resistor and the capacitor should be placed
as closely as possible to the sensor.
