Allegro MicroSystems 

ACS715

Automotive Grade, Fully Integrated, Hall Effect-Based Linear Current Sensor

with 2.1 kVRMS Voltage Isolation and a Low-Resistance Current Conductor

Description (continued)

of the device at up to 5× overcurrent conditions. The terminals of

the conductive path are electrically isolated from the sensor leads

(pins 5 through 8). This allows the ACS715 current sensor to be

used in applications requiring electrical isolation without the use

of opto-isolators or other costly isolation techniques.

The ACS715 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 device is Pb-free, except for flip-chip high-temperature

Pb-based solder balls, currently exempt from RoHS. The device is

fully calibrated prior to shipment from the factory.
