7.3.10.4.3.1 IPD Operation
IPD operates by sequentially applying six different phase patterns according to the following sequence: BC-> CB-> AB-> BA-> CA-> AC (see Figure 7-53). When the current reaches the threshold configured by IPD_CURR_THR, the MCF8316A stops driving the particular phase pattern and measures the time taken to reach the current threshold from when the particular phase pattern was applied. Thus, the time taken to reach IPD_CURR_THR is measured for all six phase patterns - this time varies as a function of the inductance in the motor windings. The state with the shortest time represents the state with the minimum inductance. The minimum inductance is because of the alignment of the north pole of the motor with this particular driving state.
