A starter motor that includes an integrated solid state switching device. The solid state switching device is mounted within the outer housing of the starter motor such that the entire starter motor can be installed as a single unit. In one embodiment, the solid state switching device includes a MOSFET positioned on the low side of the starter motor. The solid state switching device opens and closes to control the flow of current through the starter motor. In another embodiment, the solid state switching device is positioned on the high side of the starter motor. The solid state switching device can include a speed sensing circuit to prevent operation of the starter motor when the internal combustion engine is operation, a crank limiting circuit that limits the amount of time the starter motor can operate without starting the internal combustion engine and/or a thermal limiting circuit to prevent operation during overheating of the starter motor.
