Fully Integrated, Hall Effect-Based Linear Current Sensor

with Voltage Isolation and a Low-Resistance Current Conductor

The Allegro ACS704 family of current sensors provides economical and

precise solutions for current sensing in industrial, automotive, commercial, and

Package LC

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 sensor 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 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.

Pin 1: IP+

Pin 2: IP+

Pin 3: IP–

Pin 4: IP–

Pin 5: GND

Pin 6: VOUT

Pin 7: VOUT

Pin 8: VCC

The output of the device has a positive slope (>V_CC/ 2) when an increasing

current flows through the primary copper conduction path (from pins 1 and 2, to

pins 3 and 4), which is the path used for current sensing. 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 3× overcurrent

conditions. The terminals of the conductive path are electrically isolated from the

sensor leads (pins 5 through 8). This allows the ACS704 family of sensors to be

used in applications requiring electrical isolation without the use of opto-isolators

or other costly isolation techniques.

Nominal Operating Temperature, T_A

Range E............................................ –40 to 85ºC

Overcurrent Transient Tolerance*, I_P................ 60 A

^*100 total pulses, 250 ms duration each, applied at a rate of

1 pulse every 100 seconds.

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-tem-

perature Pb-based solder balls, currently exempt from RoHS and WEEE. The

device is fully calibrated prior to shipment from the factory.
