Functional Description
OPERATION
The output of these devices switches low (turns on) when a
magnetic field (south polarity) perpendicular to the Hall ele-
ment exceeds the operate point threshold, B
OP
. After turn-on,
the output is capable of sinking 25 mA and the output voltage is
V
OUT(SAT)
. When the magnetic field is reduced below the release
point, B
RP
, the device output goes high (turns off). The differ-
ence in the magnetic operate and release points is the hysteresis,
B
hys
, of the device. This built-in hysteresis allows clean switch-
ing of the output, even in the presence of external mechanical
vibration and electrical noise.
Powering-on the device in the hysteresis region, less than B
OP
and
higher than B
RP
, allows an indeterminate output state. The correct
state is attained after the first excursion beyond B
OP
or B
RP
.
CONTINUOUS-TIME BENEFITS
Continuous-time devices, such as the A110x family, offer the
fastest available power-on settling time and frequency response.
Due to offsets generated during the IC packaging process,
continuous-time devices typically require programming after
packaging to tighten magnetic parameter distributions. In con-
trast, chopper-stabilized switches employ an offset cancellation
technique on the chip that eliminates these offsets without the
need for after-packaging programming. The tradeoff is a longer
settling time and reduced frequency response as a result of the
chopper-stabilization offset cancellation algorithm.
The choice between continuous-time and chopper-stabilized
designs is solely determined by the application. Battery manage-
ment is an example where continuous-time is often required. In
these applications, V
CC
is chopped with a very small duty cycle
in order to conserve power (refer to figure 2). The duty cycle
is controlled by the power-on time, t
PO
, of the device. Because
continuous-time devices have the shorter power-on time, they
are the clear choice for such applications.
For more information on the chopper stabilization technique,
refer to Technical Paper STP 97-10, Monolithic Magnetic Hall
Sensing Using Dynamic Quadrature Offset Cancellation and
Technical Paper STP 99-1, Chopper-Stabilized Amplifiers with a
Track-and-Hold Signal Demodulator.
Figure 1. Switching Behavior of Unipolar Switches. On the horizontal axis, the B+ direction indicates increasing south polarity magnetic field
strength, and the B direction indicates decreasing south polarity field strength (including the case of increasing north polarity). This behavior can
be exhibited when using a circuit such as that shown in Panel B.
