MAXQ3181-RAN - Brand New Maxim Integrated Analog Front End (AFEs)
-
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 computed 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.
