ACS781LLRTR-050U-T Overview
As a safety precaution, the current sensors are packaged in 7-PowerSMD Module packages. A Tape & Reel (TR) package protects these current sensors from damage. Ideally, these current sensors should supply a maximum current of 15mA. There is a termination of 7 on the current sensors. During operation, these current sensors are capable of supplying a voltage of 3.3V. Current sensors should supply a minimum voltage of 3V. There should be no voltage greater than 3.6V supplied by current sensors.
