摘要： A controller for power devices which is not required to individually insulate high and low potential portions and to include an insulated power supply is disclosed. An external controller (6) is connected to a second internal control circuit (4) which is in turn connected to a level shift circuit (5) and a gate electrode of a transistor (Q2). Power supply voltage (V1) is applied to the second internal control circuit (4) for operation thereof. The level shift circuit (5) is connected to a first internal control circuit (3) which is in turn connected to a gate electrode of a transistor (Q1) and a charge pump circuit (7). Control of a first semiconductor circuit is made through the level shift means in response to an input signal generated on the basis of a second main power supply potential, thereby achieving increased responsiveness of the power devices to a control signal and improved integration.

摘要： On the p.sup.- substrate, the n.sup.- epitaxial layer is surrounded and isolated by the p well. In the surface of the n.sup.- epitaxial layer, there is provided the p floating region in the vicinity of the p well, on which the sense electrode is provided. The insulation film and the conductive film are formed on the n.sup.- epitaxial layer between the p well and the p floating region to overlap them. The conductive film and the p floating region serve as a composite field plate, which makes it hard that the surface electric field distribution is influenced by the state of electric charge in the surface and relieves the surface electric field by expanding the depletion layer, which extends from the pn junction between the n.sup.31 epitaxial layer and the p well into the n.sup.- epitaxial layer in current blocking state, toward the center of the n.sup.- epitaxial layer. The potential of the p floating region is determined by capacity coupling in the current blocking state and thus the sense voltage characteristics through the sense electrode can be smooth.

摘要： A capacitor (C) and a Zener diode (ZD2) are connected in parallel to a high-voltage side drive circuit (2). when a Zener voltage (VZD2) is set 5V, a voltage which is charged up in the capacitor (C) is determined by the Zener voltage (VZD2). Hence, it is only necessarv to set a voltage (VCC) in a loxv-voltage d.c. power source (4) at a value which is higher than (VZD2+VD+VCE), where VD is a forward-direction voltage to a diode (Di) and VCE is an ON-voltage to a low-voltage side switching device (Q1). Since a variation in a charging voltage which is supplied to a high-voltage side drive circuit is suppressed, it is possible to drive a switching device with 5V.
