ACS704ELC-005
The Allegro ACS704 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, switched-mode 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 surface of the die. Applied current flowing
through this copper conduction path generates a magnetic field which the
integrated 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 (>V
flows through the primary copper conduction path (from pins 1 and 2, to pins 3
and 4), which is the path used for current sampling. The internal resistance of this
conductive path is typically 1.5 mΩ, 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 (pins 5 through 8). This allows the ACS704 family to be used in
applications requiring electrical isolation without the use of opto-isolators or other
costly isolation techniques.
The ACS704 is provided in a small, surface mount SOIC8 package. The leadframe
is plated with 100% matte tin, which is compatible with standard lead (Pb) free
printed circuit board assembly processes. Internally, the flip-chip uses high-
temperature Pb-based solder balls, currently exempt from RoHS. The device is
fully calibrated prior to shipment from the factory.
