Fully Integrated, Hall Effect-Based Linear Current Sensor IC
with 3 kVRMS Voltage Isolation and a Low-Resistance Current Conductor
Features and Benefits
Description
▪ Industry-leading noise performance through proprietary
amplifier and filter design techniques
The Allegro ACS756 family of current sensor ICs provides
economicalandprecisesolutionsforACorDCcurrentsensing
in industrial, automotive, commercial, and communications
systems.Thedevicepackageallowsforeasyimplementationby
the customer. Typical applications include motor control, load
detection and management, power supplies, and overcurrent
fault protection.
▪ Total output error 0.8% at TA= 25°C
▪ Small package size, with easy mounting capability
▪ Monolithic Hall IC for high reliability
▪ Ultra-low power loss:130 μΩ internal conductor resistance
▪ 3 kVRMS minimum isolation voltage from
pins 1-3 to pins 4-5
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
proportionalvoltage.Deviceaccuracyisoptimizedthroughthe
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.
▪ 3.0 to 5.0 V, single supply operation
▪ 3 μs output rise time in response to step input current
▪ 20 or 40 mV/A output sensitivity
▪ Output voltage proportional to AC or DC currents
▪ Factory-trimmed for accuracy
▪ Extremely stable output offset voltage
▪ Nearly zero magnetic hysteresis

1Device is factory-trimmed at 5 V, for optimal accuracy.
2Devices are programmed for maximum accuracy at 5.0 V VCC levels. The device contains ratiometry circuits that accurately alter the 0 A Output Volt-
age and Sensitivity level of the device in proportion to the applied VCC level. However, as a result of minor nonlinearities in the ratiometry circuit ad-
ditional 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.

Definitions of Accuracy Characteristics
Sensitivity (Sens). The change in device output in response to a
1A change through the primary conductor. The sensitivity is the
product of the magnetic circuit sensitivity (G/A) and the linear
IC amplifier gain (mV/G). The linear IC amplifier gain is pro-
grammed at the factory to optimize the sensitivity (mV/A) for the
half-scale current of the device.
The ratiometric change (%) in the quiescent voltage output is

Noise (VNOISE). The noise floor is derived from the thermal and
shot noise observed in Hall elements. Dividing the noise (mV)
by the sensitivity (mV/A) provides the smallest current that the
device is able to resolve.

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
IOUT(Q) = 2.5 V. Variation in VOUT(Q) can be attributed to the res-
olution of the Allegro linear IC quiescent voltage trim, magnetic
hysteresis, and thermal drift.
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 current. The following equation is used to derive
the linearity:
V
Electrical offset voltage (VOE). The deviation of the device out-
put 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 material used as a flux concentrator.
The larger magnetic offsets are observed at the lower operating
temperatures.

actual output from its ideal value, also referred to as accuracy,

IOUT_half-scale amperes = the output voltage (V) when the

Symmetry (ESYM). The degree to which the absolute voltage
output from the IC varies in proportion to either a positive or
negative half-scale primary current. The following equation is
used to derive symmetry:
ETOT is divided into four areas:
0 A at 25°C. Accuracy at the zero current flow at 25°C, with-

Half-scale current at 25°C. Accuracy at the the half-scale current

Ratiometry. The device features a ratiometric output. This
means that the quiescent voltage output, VIOUTQ, and the mag-
netic sensitivity, Sens, are proportional to the supply voltage, VCC

Definitions of Dynamic Response Characteristics
Power-On Time (tPO). When the supply is ramped to its operat-
ing 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.

Chopper Stabilization Technique
Chopper Stabilization is an innovative circuit technique that is
This technique is made possible through the use of a BiCMOS
used to minimize the offset voltage of a Hall element and an asso- process that allows the use of low-offset and low-noise amplifiers
ciated on-chip amplifier. Allegro patented a Chopper Stabiliza-
tion technique that nearly eliminates Hall IC output drift induced
by temperature 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 magnetically induced signal in the frequency domain.
Then, using a low-pass filter, the modulated DC offset is sup-
pressed 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.
