The VMOS driving circuit comprises a first relay and the like, wherein the first relay is connected with a drain of a first triode; a first resistor is connected with a second resistor in series; the first resistor and the second resistor are both connected with a gate of the first triode; a sixth resistor is connected in series with a seventh resistor; the sixth resistor, an eighth resistor, a ninth resistor, a tenth resistor and an eleventh resistor are connected in series with a source of the first triode; the first resistor, a twelfth resistor and a thirteenth resistor are connected with a second relay; the seventh resistor is connected witha drain of a second triode; and a third relay is connected with a source of the second triode. The VMOS driving circuit and the control method thereof have the advantages of flexible application, fastresponse speed and high reliability, and support the integrated design.

Description

technical field [0001] The present invention relates to a VMOS (V-groove Metal-Oxide Semiconductor. V-groove MOS field triode) drive circuit and a control method thereof, in particular to a VMOS drive circuit and a control method of a spaceborne pyrotechnic product. Background technique [0002] The explosive device is an important part of the satellite platform, which is used to realize the deployment of sailboards, antennas and other mechanisms. At present, satellite pyrotechnic products use relays for single-ended control. The circuit of this control mode takes up a large space, is heavy in weight, and has a low degree of integration. [0003] With the rapid expansion of satellite applications, users have more diverse requirements for satellite functions, and the design of satellite structures and payloads is becoming more and more complex. It is difficult for pyrotechnics control technology to adapt to new application requirements. Contents of the invention [0004]...
