Minimize Short-Circuit Current Pulse in Hot-Swap Controller


关键词: hot-swap controllers, inrush current, circuit protection, short-circuit current 



Abstract: Because of internal circuit-breaker delay and limited MOS-gate pulldown current, many hot-swap controllers do not limit current during the first 10µs to 50µs following a shorted output. The result can be a brief flow of several hundred amperes. A simple external circuit counters this problem by minimizing the initial current spike and terminating the short circuit within 200ns to 500ns.
