Hall Effect Sensor Family
in CMOS technology

Release Notes: Revision bars indicate significant
changes to the previous edition.

1. Introduction

The HAL5xx 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 output
transistor. The comparator compares the actual mag-
netic 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
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 ro-
bust against mechanical stress effects.

The sensors are designed for industrial and automotive
applications and operate with supply voltages from
3.8 V to 24 V in the ambient temperature range from
�40

�

C up to 150

�

All sensors are available in a SMD-package (SOT-89B)
and in a leaded version (TO-92UA).

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

-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 mag-

netic fields up to 10 kHz

� constant 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 mag-
netic characteristics

� ideal sensor for applications in extreme automotive

and industrial environments

� EMC corresponding to DIN 40839

1.2. Family Overview

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

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 output
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 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 mag-
netic 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 magnet-
ic 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.

1.3.1. Special Marking of Prototype Parts

Prototype parts are coded with an underscore beneath the
temperature range letter on each IC. They may be used

for lab experiments and design-ins but are not intended to
be used for qualification tests or as production parts.

1.4. Operating Junction Temperature Range

The Hall sensors from Micronas are specified to the chip
temperature (junction temperature T

A: T

= �40

�

C to +170

�

K: T

= �40

�

C to +140

�

Note: Due to the high power dissipation at high current
consumption, there is a difference between the ambient
temperature (T

) and junction temperature. Please refer

to section 5.1. on page 40 for details.

2. Functional Description

The HAL 5xx 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.

Magnetic offset caused by mechanical stress is com-
pensated for by using the "switching offset compensa-
tion technique". Thus, an internal oscillator provides a
two-phase clock. The Hall voltage is sampled at the end
of the first phase. At the end of the second phase, both
sampled and actual Hall voltages are averaged and
compared with the actual switching point. Subsequently,
the open drain output switches to the appropriate state.
The time from crossing the magnetic switching level to
switching of output can vary between zero and 1/f

Shunt protection devices clamp voltage peaks at the
Output-Pin and V

-Pin together with external series

resistors. Reverse current is limited at the V

-Pin by an

internal series resistor up to �15 V. No external reverse
protection diode is needed at the V

-Pin for reverse

voltages ranging from 0 V to �15 V.
