DEVICE FOR SWITCHING BLOWER MOTOR FOR VEHICLES |
摘要 |
PURPOSE: A switching device of a blower motor for a vehicle is provided to multiply an allowable current and decrease a heat radiation by controlling the power supply supplying to a blower motor because two FETs(Field Effect Transistor) are connected in a row inside of one package and the FETs are synchronized. CONSTITUTION: A switching device of a blower motor for a vehicle comprises a first FET, a second FET, a first current voltage measuring unit, a second current voltage measuring unit, and a controlling unit. The first and second FETs are connected in a row, thereby controlling a voltage applied to the blower motor. The first and second current voltage measuring units respectively measure a drain current and drain voltage of the first and second EFTs. The drain currents measured by the first and second current voltage measuring units are accorded.
