General Description

The MAXQ3181 is a dedicated electricity measurement

front-end that collects and calculates polyphase volt-

age, current, active power and energy, and many other

metering parameters of a polyphase load. The comput-

ed 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.

The MAXQ3181 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.
