High-Precision Linear Hall-Effect-BasedACS780xLRCurrent Sensor IC With 200 µΩ Current ConductorDESCRIPTION (CONTINUED) path (from terminal 5 to terminal 6), which is the path used for 7), allowing the device to operate safely with voltages up to 100 V current sampling. The internal resistance of this conductive path is peak on the primary conductor. 200 µΩ typical, providing low power loss. The device is fully calibrated prior to shipment from the factory. The thickness of the copper conductor allows survival of the device The ACS780xLR family is lead (Pb) free. All leads are plated with at high overcurrent conditions. The terminals of the conductive path 100% matte tin, and there is no Pb inside the package. The heavy are electrically isolated from the signal leads (pins 1 through 4, and gauge leadframe is made of oxygen-free copper.
