Overview
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 differential inputs, a precision voltage reference, a temperature sensor, and a supply voltage generator that is energized by power pulses from the host SoC.
In conjunction with the host metering SoCs, the isolated sensor ICs offer unprecedented BOM cost reduction, immunity to magnetic tampering, and enhanced reliability for single-phase and polyphase applications.
The isolated sensor ICs operate over the industrial temperature range and are available in lead (Pb)-free SOIC-8 packages.
