Block Diagram and Sample Application Circuit
(Sample application: PAM drive, FET output)
Note: For applications where the motor has variable speed and control at low motor voltages is required, the base voltage of the
output interface transistor must be made low. In this case, a P-channel FET which can be used at low gate voltages must be
selected.
