19-1988; Rev 3; 8/03 -100V SOT23 Simple Swapper Hot-Swap Controllers General Description The MAX5900/MAX5901 are SOT23 hot-swap controllers that allow a circuit card to be safely hot-plugged into a live backplane without causing a glitch on the power-supply rail. These devices operate from -9V to -100V and provide the simplest hot-swap solution by eliminating all external components except an external N-channel MOSFET. The MAX5900/MAX5901 limit the inrush current to the load and provide a circuit-breaker function for overcurrent protection. During startup, the circuit breaker function is disabled and the MAX5900/MAX5901 limit the inrush current by gradually turning on the external MOSFET.
