MAXQ3180

Low-Power, Multifunction, Polyphase AFE

The Industry's Most Complete Polyphase Multifunction Metering AFE at the Lowest Power


Please check latest availability status for a specific part variant.

Description

The MAXQ3180 is a dedicated electricity measurement front-end that collects and calculates polyphase voltage, current, power, energy, and many other metering and power-quality 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 MAXQ3180 and monitor the status of operations.

The MAXQ3180 performs voltage and current measurements using an integrated ADC that can measure up to seven external differential signal pairs. An eighth differential signal pair is used to measure the die temperature. An internal amplifier automatically adjusts the current channel gain to compensate for low-current channel-signal levels.
