Not for New Design

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

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

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)

VIOUT(Q) – VIOUT_–half-scale amperes



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:

5 V

IOUTQ(V

and the ratiometric change (%) in sensitivity is defined as:

VCC 5 V

∆Sens(∆V)

Sens

(5V)

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.
