Configuration
As shown in the table below four PWM output signals and two analog feedback signals interface between the
MC58113 IC and the DK58113’s switching amplifier.
2.3.3 Step Motor Drive
Figure 2-5 shows the arrangement of the DK58113’s amplifier stage when the MC54113 IC is used, or when the
MC58113 IC is used with the two-phase step motor type selected.
