ACS711
Description (continued)
of the copper conductor allows survival of the device at up to 5×
overcurrent conditions.
The ACS711 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.
