Description
The Allegro ACS75x family of current sensor ICs provides
economical and precise solutions for 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 typically 130 μΩ, providing low power loss. The thickness
of the copper conductor allows survival of the device at up to

ACS750xCA-75
Fully Integrated, Hall Effect-Based Linear Current Sensor IC
with High Voltage Isolation and a Low-Resistance Current Conductor
Description (continued)
5× overcurrent conditions. The terminals of the conductive path are
electrically isolated from the signal leads (pins 1 through 3). This
allows the ACS75x 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 pins are coated with
100% matte tin, and there is no lead inside the package. The
heavy gauge leadframe is made of oxygen-free copper.

2Variant is in production but has been determined to be LAST TIME BUY. This classification indicates that the variant is obsolete and notice
has been given. Sale of the variant is currently restricted to existing customer applications. The variant should not be purchased for new de-
sign applications because of obsolescence in the near future. Samples are no longer available. Status date change: April 28, 2008. Deadline
for receipt of LAST TIME BUY orders is October 31, 2008.
