Figure 2-12. Three-Phase Current Regulator Circuit
Pins 1-18 and 2-17 “Personality module” RCN1 provide gain compensation for phase
“A” regulator circuit. Similar compensation is provided for phase “B” and “C” circuits as
shown in Figure 2-12. The default values for these selectable components (RCN1) are
shown in Figure 2-12.
Connection IFDBK (pin 12 of P1) is provided for monitoring phase “A” current. For DC
brushless motor operation, the signal at this pin would represent motor phase “A” current.
For DC brush motor operation, this signal would represent the current flowing in the
motor armature.
