Hall Effect Linear Current Sensor with Overcurrent
Fault Output for < 100 V Isolation Applications
ACS711
Description (continued)
of the copper conductor allows survival of the device at up to 5×
overcurrent conditions.
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.
TheACS711 is provided in small, surface mount packages: SOIC8
and QFN12. The leadframe is plated with 100% matte tin, which
is compatible with standard lead (Pb) free printed circuit board
