ACS756xCB
The Allegro ACS756 family of current sensor ICs provides
economical and precise solutions for AC or DC current sensing
in industrial, automotive, commercial, and communications
systems. The device package allows for easy implementation by
the customer. Typical applications include motor control, load
detection and management, power supplies, and overcurrent
fault protection.
The device consists of a precision, low-offset linear Hall
circuit with a copper conduction path located near the die.
Applied current flowing through this copper conduction path
generates a magnetic field which the Hall IC converts into a
proportional voltage. Device accuracy is optimized through the
close proximity of the magnetic signal to the Hall transducer.
A precise, proportional voltage is provided by the low-offset,
chopper-stabilized BiCMOS Hall IC, which is programmed
for accuracy at the factory.
The output of the device has a positive slope (>VCC
/ 2) when an
increasing current flows through the primary copper conduction
path (from terminal 4 to terminal 5), which is the path used
for current sampling. The internal resistance of this conductive
path is 100 µΩ typical, providing low power loss.
The thickness of the copper conductor allows survival of the
device at up to 5× overcurrent conditions. The terminals of the
conductive path are electrically isolated from the signal leads

[2] Devices are programmed for maximum accuracy at 5.0 V VCC levels. The device contains ratiometry circuits that accurately alter the 0 A Output Voltage and Sensitivity
level of the device in proportion to the applied VCC level. However, as a result of minor nonlinearities in the ratiometry circuit additional output error will result when VCC
varies from the 5 V VCC level. Customers that plan to operate the device from a 3.3 V regulated supply should contact their local Allegro sales representative regarding
expected device accuracy levels under these bias conditions.

Sensitivity (Sens)
The change in device output in response to a 1 A change through
the primary conductor. The sensitivity is the product of the mag-
netic circuit sensitivity (G / A) and the linear IC amplifier gain
(mV/G). The linear IC amplifier gain is programmed at the factory
to optimize the sensitivity (mV/A) for the half-scale current of the
device.
Noise (VNOISE)
The noise floor is derived from the thermal and shot noise
observed in Hall elements. Dividing the noise (mV) by the sensi-
tivity (mV/A) provides the smallest current that the device is able
to resolve.
Nonlinearity (ELIN)
The degree to which the voltage output from the IC varies in
direct proportion to the primary current through its half-scale
amplitude. Nonlinearity in the output can be attributed to the
saturation of the flux concentrator approaching the half-scale cur-
rent. The following equation is used to derive the linearity:
100 1–
[{
[{
VIOUT_half-scale amperes VIOUT(Q)
gain × % sat ( )
2 (VIOUT_quarter-scale amperes VIOUT(Q) )
where
∆ gain = the gain variation as a function of temperature
changes from 25°C,
% sat = the percentage of saturation of the flux concentra-
tor, which becomes significant as the current being sampled
approaches half-scale ±IP , and
VIOUT_half-scale amperes = the output voltage (V) when the
sampled current approximates half-scale ±IP .
Symmetry (ESYM)
The degree to which the absolute voltage output from the IC
varies in proportion to either a positive or negative half-scale pri-
mary current. The following equation is used to derive symmetry:
100
VIOUT_+ half-scale amperes VIOUT(Q)

Ratiometry
The device features a ratiometric output. This means that the qui-
escent voltage output, VIOUTQ, and the magnetic sensitivity, Sens,
are proportional to the supply voltage, VCC.
The ratiometric change (%) in the quiescent voltage output is
defined as:

Quiescent Output Voltage (VIOUT(Q))
The output of the device when the primary current is zero. For
a unipolar supply voltage, it nominally remains at VCC ⁄ 2. Thus,
VCC = 5 V translates into VIOUT(Q) = 2.5 V. Variation in VOUT(Q)
can be attributed to the resolution of the Allegro linear IC quies-
cent voltage trim, magnetic hysteresis, and thermal drift.
Electrical Offset Voltage (VOE)
The deviation of the device output from its ideal quiescent value
of VCC ⁄ 2 due to nonmagnetic causes.
Magnetic Offset Error (IERROM)
The magnetic offset is due to the residual magnetism (remnant
field) of the core material. The magnetic offset error is highest
when the magnetic circuit has been saturated, usually when the
device has been subjected to a full-scale or high-current overload
condition. The magnetic offset is largely dependent on the mate-
rial used as a flux concentrator. The larger magnetic offsets are
observed at the lower operating temperatures.
Total Output Error (ETOT)
The maximum deviation of the actual output from its ideal value,
also referred to as accuracy, illustrated graphically in the output
voltage versus current chart on the following page.
ETOT is divided into four areas:
0 A at 25°C. Accuracy at the zero current flow at 25°C,
without the effects of temperature.
0 A over Δ temperature. Accuracy at the zero current flow
including temperature effects.
Half-scale current at 25°C. Accuracy at the the half-scale current
at 25°C, without the effects of temperature.
Half-scale current over Δ temperature. Accuracy at the half-scale
current flow including temperature effects.

Power-On Time (tPO)
When the supply is ramped to its operating voltage, the device
requires a finite time to power its internal components before
responding to an input magnetic field.
Power-On Time, tPO , is defined as the time it takes for the output
voltage to settle within ±10% of its steady state value under an
applied magnetic field, after the power supply has reached its
minimum specified operating voltage, VCC(min), as shown in the
chart at right.
Rise Time (tr)
The time interval between a) when the device reaches 10% of its
full scale value, and b) when it reaches 90% of its full scale value.
The rise time to a step response is used to derive the bandwidth
of the device, in which ƒ(–3 dB) = 0.35 / tr. Both tr and tRESPONSE
are detrimentally affected by eddy current losses observed in the
conductive IC ground plane.
Propagation Delay (tPROP)
The time required for the device output to reect a change in
the primary current signal. Propagation delay is attributed to
inductive loading within the linear IC package, as well as in the
inductive loop formed by the primary conductor geometry. Propa-
gation delay can be considered as a xed time oset and may be
compensated.

Chopper Stabilization is an innovative circuit technique that is
used to minimize the offset voltage of a Hall element and an asso-
ciated on-chip amplifier. Allegro’s Chopper Stabilization tech-
nique nearly eliminates Hall IC output drift induced by tempera-
ture or package stress effects. This offset reduction technique is
based on a signal modulation-demodulation process. Modulation
is used to separate the undesired DC offset signal from the mag-
netically induced signal in the frequency domain. Then, using
a low-pass filter, the modulated DC offset is suppressed while
the magnetically induced signal passes through the filter. As a
result of this chopper stabilization approach, the output voltage
from the Hall IC is desensitized to the effects of temperature and
mechanical stress. This technique produces devices that have an
extremely stable Electrical Offset Voltage, are immune to thermal
stress, and have precise recoverability after temperature cycling.
This technique is made possible through the use of a BiCMOS
process that allows the use of low-offset and low-noise amplifiers
in combination with high-density logic integration and sample
and hold circuits.
