The from Products is a 72V simple swapper hot swap controller in 6 pin SOT-23 package. It allows circuit card to be safely hot plugged into a live backplane without causing a glitch on power supply rail. This device operates from 9V to 72V and provides simplest hot swap solution by eliminating all external components except external P-channel MOSFET. The MAX5902 limits inrush current to load and provides circuit breaker function for overcurrent protection. During start-up the circuit breaker function is disabled and MAX5902 limits inrush current by gradually turning on external MOSFET. Once the external MOSFET is fully enhanced, the circuit breaker function is enabled and device provides overcurrent protection by monitoring the voltage drop across external MOSFET"s on-resistance. It offers latched or autoretry fault management. The device is used in network routers, servers, network switches RAID and base station line cards.
