Abstract
A switching circuit has a primary MOSFET switch connected between first and second terminals that are connected to a power line and a load represented as a resistance and inductance. The primary switch is operable by primary control commands to assume a conductive or non-conductive state. Four protection branches are connected in parallel with the primary switch, each having a series connected resistive element and a secondary MOSFET switch operable by branch control commands received at branch command terminals to assume a conductive or non-conductive state. A timing circuit applies branch turn off control commands in sequence to the branch command terminals, each delayed by a different predetermined time interval relative to when a primary turn off control command is applied to the primary switch.
