SEMICONDUCTOR DEVICE WITH PROTECTIVE FUNCTIONS |
摘要 |
ABSTRACTThe semiconductor device is inserted between a power source and a load. A current flowing between an external drain terminal D and an external source terminal S is controlled in accordance with a control voltage applied between an external gate terminal G and the external source terminal S. In addition, the semiconductor device has a main MOSFET 1 and a detecting MOSFET 2 each of which is inserted between the external drain terminal D and the external source terminal S, a protective circuit 3 which protects the main MOSFET 1 by a protective transistor 5 when the abnormality is detected thereby, and an impedance element 4 inserted between the protective MOSFET 5, and a junction connecting the external gate terminal G to a gate electrode of the detecting MOSFET 2. |
