MAXQ3181 Datasheet Polyphase Afe

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4668; Rev 1; 12/09 Low-Power, Active Energy, Polyphase AFE General.

General Description

The MAXQ3181 is a dedicated electricity measurement front-end that collects and calculates polyphase voltage, current, active power and energy, and many other metering parameters of a polyphase load.

The puted results can be retrieved by an external master through the on-chip serial peripheral interface (SPI™) bus.

This bus is also used by the external master to configure the operation of the MAXQ3181 and monitor the status of operations.
