DESCRIPTION
The Allegro ACS756 family of current sensor ICs provides
economical and precise solutions forAC 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

Typical Application
The ACS756 outputs an analog signal (VOUT ) that varies linearly with the uni- or bi-directional AC or DC primary sampled current, IP ,
within the range specified. CF is for optimal noise management, with values that depend on the application.

ACS756xCB
Fully Integrated, Hall Effect-Based Linear Current Sensor IC
with 3 kVRMS Voltage Isolation and a Low-Resistance Current Conductor
Description (continued)
(pins 1 through 3). This allows the ACS756 family of sensor ICs to
be used in applications requiring electrical isolation without the use
of opto-isolators or other costly isolation techniques.
The device is fully calibrated prior to shipment from the factory.
The ACS75x family is lead (Pb) free. All leads are plated with 100%
matte tin, and there is no Pb inside the package. The heavy gauge
leadframe is made of oxygen-free copper.
