Automotive Grade, Fully Integrated, Hall Effect-Based Linear Current Sensor
with 2.1 kVRMS Voltage Isolation and a Low-Resistance Current Conductor
ACS714
Description (continued)
of the device at up to 5× overcurrent conditions. The terminals of
TheACS714 is provided in a small, surface mount SOIC8 package.
The leadframe is plated with 100% matte tin, which is compatible
withstandardlead(Pb)freeprintedcircuitboardassemblyprocesses.
Internally,thedeviceisPb-free,exceptforflip-chiphigh-temperature
Pb-based solder balls, currently exempt from RoHS. The device is
fully calibrated prior to shipment from the factory.
the conductive path are electrically isolated from the sensor leads
(pins 5 through 8). This allows the ACS714 current sensor to be
used in applications requiring electrical isolation without the use
of opto-isolators or other costly isolation techniques.
