A solid-state power distribution protection switching circuit with I~2t inverse time overcurrent/short circuit protection, on/off/overload indication and current telemetry function is designed. Accurate control of acquisition accuracy and overcurrent/short circuit protection values is achieved by current precision acquisition circuit and overcurrent/short circuit protection circuit, and the overcurrent/short circuit protection values are externally adjustable. The solid-state power distribution protection switch circuit is located and wiried based on thick film micro-assembly technology, and is assembled and produced by a hybrid integrated circuit process.Through design simulation and application testing, the circuit performance meets the design requirements, and has significant advantages in miniaturization and lightweight design.
