MAXQ3180 Maxim, MAXQ3180 Datasheet - Page 73

• Manufacturer Part Number: MAXQ3180
• 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
• Manufacturer: Maxim

These registers configure the time slot normally assigned to current channels A/B/C. We recommend leaving these
registers at their default values. If they must be reassigned, one must ensure that all the current and voltage chan-
nels are reassigned properly so that the MAXQ3180 computes the power/energy parameters as intended by your
setup.

Analog Conversion Select. This four-bit field determines which of the following analog inputs are sampled
during this time slot.
0000 = V0P - VN
0001 = V1P - VN
0010 = V2P - VN
0011 = I0P - I0N (Phase A Current: 0011)
0100 = I1P - I1N (Phase B Current: 0100)
0101 = I2P - I2N (Phase C Current: 0101)
0110 = INP - VN
1xxx = Temperature
All other values are reserved.
ADC Disable. When set, disables the ADC for this time slot.
