Abstract
A single low side power transistor switch is used to efficiently control a brushed motor in a forward rotational direction. A boost voltage power supply is used to supply voltage to the brushed motor in a reverse rotational direction and/or braking from the forward rotational direction. A digital device controls the brushed motor rotational speed and rotational directions.
