This ti Design uses Texas Instruments' Hall sensing technology to provide a solution for knowing how much AC current is flowing through a wire without any physical intervention. TIDA-00218 implements a flux concentrator to concentrate the flux around the AC current-carrying wire, rather than letting (...)
