A 75-Ω resistor, for instance, would restrict current through Q2 to about 10 mA. This means R2 would only have to dissipate 7.5 mW, allowing a common 1/8-W resistor to easily withstand permanent ...

Figure 2. Another hot-swap circuit (top) implements current sensing and 2A-limiting with a pnp transistor, as illustrated by the turn-on waveforms (bottom): Ch1 = current; Ch2 = Q2 gate voltage. The ...

Trace 1 in Figure 3 depicts the start-up of a 2.4-kW power supply with the inrush-current limiter and a slow-start circuit, which allows the separation of the inrush and the start-up processes. The ...
