71M6103/71M6113/ 71M6201/71M6203/ 71M6601/71M6603 Isolated Sensor ICs DATA SHEET GENERAL DESCRIPTION The 71M6103, 71M6113, 71M6201, 71M6203, 71M6601, and 71M6603 (71M6xxx) isolated sensor ICs enable Silergy/Teridian single- and polyphase-metering systems-on-chips (SoCs) to use non-isolating sensors such as resistive shunts, eliminating the need for costly isolation transformers or CTs.
Isolation is provided by low-cost pulse transformers (PTs) that form a bidirectional digital communication link between the host SoC and the isolated sensor ICs.
Power to the isolated sensor ICs is provided via the PTs.
The 71M6xxx isolated sensor ICs contain a 22-bit delta-sigma ADC, an amplifier with diff...
