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 motor control, 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 flowing through
this copper conduction path generates a magnetic field 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 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 sensing. 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.
