To provide a motor driving overcurrent interruption circuit, a motor driving circuit, and its overcurrent interruption method.

A motor driving overcurrent interruption circuit includes a motor driving part 10 which includes a source type switching element group 11 connected to an upper side of an H-bridge and applying a supply voltage to a motor M and a sink type switching element group 13 connected to a lower side of the H-bridge and sinking a current flowing through the motor M to a sensing terminal so as to sense the current, and drives the motor M; an overcurrent sense part 30 which senses a current flowing to a switching element having been turned in the sink type switching element group 13 at the sensing terminal between a lower end of the sink type switching element group 13 and a ground power source; and an overcurrent interruption part 50 which turns on with a voltage of a sensed overcurrent, and sinks a driving control signal applied to the switching element having been turned on in the sink type switching element group 13 to the ground power source so as to interrupt the overcurrent.
