Reportedly a smaller, low-cost alternative to toroid-based sensors, the ACS754/5 family of devices are said to offer precise current sensing. The company says the ACS754 devices are bi-directional sensors, while the ACS755 versions offer single-direction sensing with approximately twice the resolution of the bi-directional ACS754 sensors. The devices provide 3-kV isolation and single voltage supply operation while placing only 100 µ? of resistance in the current path. The company offers 50-A, 100-A, 130-A, 150-A and 200-A versions. The lead-free, PC-mountable package is 14 by 22 by 7 mm and integrates the current path.
