Functional description

Figure 2 shows a typical motor control application block diagram using the IMC101T-T038. The IMC101T-T038

provides a built-in closed loop sensorless control algorithm using the unique flexible Motion Control Engine (MCE)

for permanent magnet motors. The MCE™ consists of a collection of control elements, motion peripherals, a

dedicated motion control sequencer and internal memory to map internal signal nodes. IMC101T-T038 also

employs a unique single shunt current reconstruction circuit in addition to leg shunt current sensing circuit to

eliminate additional analog/digital circuitry.
