Abstract

PURPOSE:To reduce the cost by combining the drain current and the drain-source voltage to control turning-on/off of a main MOSFET. CONSTITUTION:The power consumption in the chip of a power MOSFET is detected by the combination between a drain-source voltage VDS and a drain current ID of the power MOSFET. When relations between the voltage VDS and the current ID satisfy condition ID>AXVDS+B, a gate-source voltage VGS is reduced to turn off a load driving MOSFET. A and B in this formula are a negative constant and a positive constant respectively, and they are so selected that a maximum value of VDSXID on the operation characteristic line, namely, -B<2>/4A and a maximum allowable loss PD of the load driving MOSFET satisfy relations PD>=-B<2>/4A. Thus, an MOSFET incorporating the overpower protection function of low cost is obtained.
