Differential Hall Effect Sensor IC
in CMOS technology
Introduction
The HAL300 is a differential Hall switch produced in
CMOS technology. The sensor includes 2 temperature-
compensated Hall plates (2.05 mm apart) with active off-
set compensation, a differential amplifier with a Schmitt
trigger, and an open-drain output transistor (see Fig. 2).
The HAL300 is a differential sensor which responds to
spatial differences of the magnetic field. The Hall volt-
ages at the two Hall plates, S
1
and S
2
, are amplified with
a differential amplifier. The differential signal is
compared with the actual switching level of the internal
Schmitt trigger. Accordingly, the output transistor is
switched on or off.
The sensor has a bipolar switching behavior and re-
quires positive and negative values of
B = B
S1
– B
S2
for
correct operation.
The HAL300 is an ideal sensor for applications with a ro-
tating multi-pole-ring in front of the branded side of the
package (see Fig. 4 and Fig. 5), such as ignition timing,
anti-lock brake systems, and revolution counting.
For applications in which a magnet is mounted on the
back side of the package (back-biased applications), the
HAL320 is recommended.
The active offset compensation leads
to constant mag-
netic characteristics over supply voltage and tempera-
ture.
The sensor is designed for industrial and automotive ap-
plications and operates with supply voltages from 4.5 V
to 24 V in the ambient temperature range from –40
°
C
up to 150
°
C.
The HAL300 is available in a SMD-package (SOT-89A)
and in a leaded version (TO-92UA).
Features:
– distance between Hall plates: 2.05 mm
– operates from 4.5 V to 24 V supply voltage
– switching offset compensation at 62 kHz
– overvoltage protection
– reverse-voltage protection at V
DD
-pin
– short-circuit protected open-drain output by thermal
shutdown
– operates with magnetic fields from DC to 10 kHz
– output turns low with magnetic south pole on branded
side of package and with a higher magnetic flux densi-
ty in sensitive area S1 as in S2
– on-chip temperature compensation circuitry mini-
mizes shifts of the magnetic parameters over temper-
ature and 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 hystere-
sis
– EMC corresponding to DIN 40839
