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.
RoHS non-compliance — what it means for your BOM
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.
Lifecycle and supply posture
It is sourced through independent distribution and quoted to order against an RFQ. For volume production or blanket-order commitments, submit an RFQ with your target quantity and delivery window.
