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.Maxim > App Notes > AMPLIFIER AND COMPARATOR CIRCUITS CIRCUIT PROTECTION HOT-SWAP AND POWER SWITCHING CIRCUITS Keywords: hot-swap controllers, inrush current, circuit protection, short-circuit current Aug 27, 2004 APPLICATION NOTE 3328 Minimize Short-Circuit Current Pulse in Hot-Swap Controller Abstract: Because of internal circuit-breaker delay and limited MOS-gate pulldown current, many hot-swap controllers do not limit current during the first 10s to 50s 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. A typical +12V, 6A, hot-swap controller circuit (Figure 1) contains (like……
