Low-Power, Multifunction, Polyphase AFE
General Description
The MAXQ3180 is a dedicated electricity measurement
front-end that collects and calculates polyphase volt-
age, current, power, energy, and many other metering
and power-quality parameters of a polyphase load. The
computed results can be retrieved by an external mas-
ter through the on-chip serial peripheral interface
(SPI™) bus. This bus is also used by the external mas-
ter to configure the operation of the MAXQ3180 and
monitor the status of operations.
The MAXQ3180 performs voltage and current measure-
ments using an integrated ADC that can measure up to
seven external differential signal pairs. An eighth differ-
ential signal pair is used to measure the die tempera-
ture. An internal amplifier automatically adjusts the
current channel gain to compensate for low-current
channel-signal levels.
