Hot-swap controller for inrush limiting and fault isolation
The Maxim Integrated MAX5938LEEE is a hot-swap controller designed to manage inrush current and provide fault isolation when a circuit board is inserted into a live backplane. It controls an external N-channel MOSFET to ramp the output voltage smoothly, preventing supply droop and connector damage during hot insertion. The part is typically deployed in high-availability systems — servers, storage arrays, base stations, and industrial backplanes — where boards must be swapped without powering down the chassis.
The MAX5938LEEE is marked RoHS non-compliant. That means the part contains lead (Pb) or another restricted substance above the RoHS exemption threshold. If your end product must ship into EU, UK, or California markets under RoHS/REACH, this part triggers an exemption justification or forces a lead-free alternative. For military, aerospace, or industrial equipment with an RoHS waiver, this is not a blocker — but your quality team needs the exemption paperwork in place before the BOM is locked.
