Abstract
A drive device drives a motor serving as a load. A first upstream switch is disposed upstream from the motor and a first downstream switch is disposed downstream from the motor in a first current path of current flowing via the motor. A second upstream switch is disposed upstream from the motor and a second downstream switch is disposed downstream from the motor in a second current path of current flowing via the motor. A direction of the current flowing in the motor when current flows in the first current path is different from a direction of the current flowing in the motor when current flows in the second current path. The first upstream drive circuit stops flow of current via the first upstream switch when the current flowing through the first upstream switch becomes greater than or equal to a current threshold.
