Abstract

The invention provides a highly integrated intelligent power distribution safety switch circuit, which is characterized in that each part of the intelligent power distribution safety switch circuit is subjected to chip collection design and integrated design to form three main chips, namely an isolation control chip, an isolation driving chip and a VDMOS (Vertical Double-diffused Metal Oxide Semiconductor) tube, and the three main chips are subjected to integrated assembly through a hybrid integrated circuit process; main circuit isolation control, I2T over-current protection, short-circuit protection, over-temperature protection, switch state feedback and tripping state feedback of the intelligent power distribution switch are integrated into two special chips, and the special chips and a VDMOS tube are adopted to develop the intelligent power distribution safety switch circuit, so that the size of the power distribution switch is greatly reduced; according to the invention, full-localized 0V-100V and 1A-25A intelligent power distribution safety switch series products suitable for aerospace models can be developed, and the circuit size is reduced by more than 1 / 3 compared with that of foreign like products. The requirements of intelligence, miniaturization and localization of the aerospace intelligent power distribution safety switch are met.

Description

technical field [0001] The invention belongs to the design technology of semiconductor hybrid integrated circuits, in particular to a highly integrated intelligent power distribution safety switch circuit. Background technique [0002] Smart power distribution is a major development direction of power electronics technology. Smart power distribution can realize self-detection of power distribution equipment, autonomous management of loads, effective isolation and recovery in the event of partial faults, and improve the intelligence of power distribution systems. With the integration and intelligentization of power distribution systems such as satellites and missiles, the development trend of intelligent power distribution is developing in the direction of high power, integration, intelligence and systematization. [0003] Most of the intelligent power distribution products in the prior art are large in size, which cannot meet the intelligent, miniaturized, and modular requir...
