This structure avoids the impurity particles in the prior art that tend to Defects attached to the high-voltage drive circuit that will adversely affect the performance of the high-voltage drive circuit maintain a stable output state and will not burn out subsequent devices.

Description

technical field [0001] The invention belongs to the technical field of driving, and in particular relates to a high-voltage driving circuit device with a particle barrier. Background technique [0002] With the rapid development of intelligent power integrated circuits, the design of high-voltage chips has attracted more and more attention. High-voltage drive circuit is an indispensable part of high-voltage chip design, which requires large drive capability, high withstand voltage, low power consumption and high reliability. At the same time, because the control level is low-voltage logic, the design of the high-voltage level conversion circuit is also very important. With the improvement of integration, the trend of miniaturization of high-voltage drive circuit is getting higher and higher, which will inevitably increase the temperature of high-voltage drive circuit, which will affect the normal operation of the equipment. Therefore, it is necessary to make the high-voltag...

With the improvement of integration, the trend of miniaturization of high-voltage drive circuit is getting higher and higher, which will inevitably increase the temperature of high-voltage drive circuit, which will affect the normal operation of the equipment. Therefore, it is necessary to make the high-voltage drive circuit around The ambient air keeps flowing and takes away the heat of the high-voltage drive circuit from time to time. However, because the air often contains a large number of impurity particles, these impurity particles tend to adhere to the high-voltage drive circuit, which will also affect the performance of the high-voltage drive circuit.
