Differential Hall Effect Sensor IC
in CMOS technology
Introduction
The HAL320 is a differential Hall switch produced in
CMOS technology. The sensor includes 2 temperature-
compensated Hall plates (2.25 mm apart) with active off-
set compensation, a differential amplifier with a Schmitt
trigger, and an open-drain output transistor (see Fig. 2).
The HAL320 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 requires positive and negative values of
B = B
S1
– B
S2
for correct operation.
Basically, there are two ways to generate the differential
signal
B:
– Rotating a multi-pole-ring in front of the branded side
of the package (see Fig. 4, Fig. 5, and Fig. 6).
– Back-bias applications:
A magnet on the back side of the package generates
a back-bias field at both Hall plates. The differential
signal
B results from the magnetic modulation of the
back-bias field by a rotating ferromagnetic target.
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 HAL320 is an ideal sensor for target wheel applica-
tions, ignition timing, anti-lock brake systems, and revo-
lution counting in extreme automotive and industrial en-
vironments
The HAL320 is available in two SMD-packages
(SOT-89A and SOT-89B) and in a leaded version
(TO-92UA).
Features:
– distance between Hall plates: 2.25 mm
– operates from 4.5 V to 24 V supply voltage
– switching offset compensation at 62 kHz
– overvoltage protection
– reverse-voltage protection of 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
– EMC corresponding to DIN 40839
