Isolated Sensor ICs
DATA SHEET
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.
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.
