Abstract: A solid-state power distribution protection switching circuit with I2t 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 valuesisachieved by current precision acquisition circuit and overcurrent/short circuit protection circuit,and the overcurrent/short circuit protection values are externally adjustable.Thesolid-statepower distribution protection switch circuit islocated 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 performancemeetsthedesign requirements,and hassignificantadvantagesinminiaturizationand lightweightdesign.

Key words: solid state power distribution protection switch, overcurrent/short circuit protection, micro assembly technology, hybrid integrated circuit
