Dual Hall-Effect Sensor with Independent Outputs
1. Introduction
The HAL 700 is a monolithic CMOS Hall-effect sensor
consisting of two independent latched switches (see
Fig. 3–3) with closely matched magnetic characteris-
tics controlling two independent open-drain outputs.
The Hall plates of the two switches are spaced
2.35 mm apart.
In combination with an active target providing a
sequence of alternating magnetic north and south
poles, the sensor forms a system generating the sig-
nals required to control position, speed, and direction
of the target movement.
The device includes temperature compensation and
active offset compensation to provide excellent stability
and matching of the switching points in the presence of
mechanical stress over the whole temperature- and
supply voltage range. This is required by systems
which determine the direction by comparing two trans-
ducer signals.
The sensor is designed for industrial and automotive
applications and operates with supply voltages from
3.8 V to 24 V in the ambient temperature range from
40
°
C up to 125
°
C.
The HAL 700 is available in the SMD package
SOT-89B.

– multipole magnet applications,
– rotating speed and direction measurement,
position tracking (active targets), and
– window lifters.
