GENERAL DESCRIPTION
The 71M6103/71M6113/71M6201/71M6203/71M6601/71M6603 (71M6xxx) isolated sensor ICs enable Maxim Integrated’s 4th-generation polyphase-metering 71M654x systems-on-chips (SoCs) to use nonisolating sensors such as resistive shunts without the need for costly and nonlinear isolation transformers or CTs. Isolation is provided by low-cost pulse transformers that form a bidirectional digital communication link between the 71M654x and the isolated sensor ICs.
