Hot swap controller for board-level power management
The MIC25383R-JBQS is a single channel hot swap controller from Microchip Technology, designed to manage inrush current and protect downstream circuitry during board insertion into a live backplane. This part is classified under Discrete Semiconductors and is supplied in Bulk packaging, which suits prototype builds and low-to-medium volume production runs where tape-and-reel feed isn't required.
Active lifecycle — sourcing posture
Microchip lists the MIC25383R-JBQS lifecycle stage as Active, meaning the manufacturer continues to support it for new designs and production orders.
The Bulk package designation indicates the devices are shipped loose in tubes or trays, not on reels — a detail that matters for pick-and-place setup if the line expects tape feed. As a single-channel controller, it occupies a compact footprint on the PCB, suitable for point-of-load hot swap in servers, storage arrays, and telecom line cards where each board slot needs independent current limiting.
