Advanced Register Configurations

Analog Scan Configuration Registers

Time Slot Assignment—Current Channel X = A/B/C (SCAN_IX)

(A: 0x008, B: 0x00C, C: 0x00A)

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 MAXQ3183 computes the power/energy parameters as intended by your

setup.

ADCMX

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.

DADCNV

ADC Disable. When set, disables the ADC for this time slot.
