Allegro MicroSystems 

ACS711

Hall Effect Linear Current Sensor with Overcurrent

Fault Output for < 100 V Isolation Applications

Description (continued)

of the copper conductor allows survival of the device at up to 5×

overcurrent conditions.

The ACS711 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

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.
