GENERAL DESCRIPTION

The 71M6103/71M6113/71M6201/71M6203/71M6601/71M6603

(71M6xxx) isolated sensor ICs enable Maxim Integrated’s 4th-

generation

(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.

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 provided by the 71M654x.

In conjunction with the 71M654x metering SoCs, the isolated

sensor ICs offer unprecedented BOM cost reduction, immunity to

magnetic tampering, and enhanced reliability for single-phase

and polyphase applications.
