Description

technical field [0001] The invention relates to a module integrated with isolated power supply and MOSFET drive and detection functions. Background technique [0002] In aerospace systems, the driving circuit for MOSFET devices is usually composed of isolated power supply, driving circuit and state detection feedback circuit, which requires many devices, occupies a large board area, and the reliability of each part is uneven. Therefore, in the existing application field, there is no device that integrates the functions of MOSFET drive circuit, isolated power supply, signal isolation transmission, and switch state detection. The functions of each part are scattered, occupying a large board area, and the reliability is uneven. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, to provide a module integrating isolated power supply and MOSFET drive and detection functions, and to realize the appl...
