Abstract—Purpose of this paper is to describe the hardware design implementation of hot-swap controller. The Hot-swap circuit protects load, minimizes inrush current and safely shutdown in the event of a fault. The programmable fault current threshold starts the fault

timer while allowing the current to pass to the load uninhibited. The programmable current limit threshold sets the maximum current allowed into the load, for both inrush and severe load faults. Both events use the programmable timer which inhibits all current to the load when it expires. The fault and power good out puts are used for improved system management and sequencing control.
 

Index Terms—hot-swap controller, inrush current, power good pin, MOSFET.
