Loop Current Sense Value.
Holds the realtime measured loop current. 0 to 101.09 mA measurement range,
3.097 µ A/LSB, 500 µ A effective resolution. 800 Hz update rate, signed/magnitude.
IRING (Transistor Q5) Current Measurement.
Reflects the current flowing into the IRING pin of the Si3200 (transistor Q5 of a dis-
crete circuit). 3.097 µ A/LSB, 2’s complement.
IRINGN (Transistor Q3) Current Measurement.
Reflects the current flowing into the IRINGN pin of the Si3200 (transistor Q3 of a dis-
crete circuit). 195.3 nA/LSB, 2’s complement.
