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]...
