                                                ACS781LLRTR-100B-T Overview
For safety reasons, the current sensors are enclosed in 7-PowerSMD Module packages. As a safety measure, the current sensors are packaged inside the Tape & Reel (TR) to prevent damage to the devices. Ideally, these current sensors should supply a maximum current of 15mA. The current sensors have 7 terminations. As long as these current sensors are working, they can supply a voltage of 3.3V. ldeally, current sensors should supply 3V voltage. Nevertheless, the voltage supplied by current sensors should not exceed 3.6V.
