Current Sensor: ACS755xCB-150

The Allegro ACS75x family of current sensors 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 load detection and management, power

supplies, and overcurrent fault protection.

The device consists of a precision, low-offset linear Hall sensor circuit with a

copper conduction path located near the die. Applied current

ﬂ

owing through

this copper conduction path generates a magnetic

ﬁ

eld which is sensed by the

integrated Hall IC and converted 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 will be valid when the current

ﬂ

ows from pin 4 to pin 5.

The internal resistance of this conductive path is typically 100

μΩ,

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 sensor leads (pins 1 through 3). This allows the

ACS75x family of sensors 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-free. All leads are coated with 100% matte tin, and there is no lead

inside the package. The heavy gauge leadframe is made of oxygen-free copper.
