The Texas Instruments TPS24751RUVR is a single-channel general-purpose hot swap controller operating from a 2.5V to 18V supply. It is supplied in a 36-pin VQFN package measuring 7mm by 3.5mm at 1mm high, on tape and reel in quantities of 3, 000. The device is rated for -40°C to 85°C, carries MSL 2 moisture sensitivity classification, and is classified EAR99 for export. TPS24751RUVR is an active production part in the TI TPS24751 series.

A hot swap controller manages the moment a board or module is inserted into a live system, ramping current into the load capacitance in a controlled way so the backplane rail does not collapse and the inrush does not damage connectors or components. It also provides the overcurrent and fault protection that lets a failed card be isolated without taking down the rail feeding its neighbours. Controllers in this class are designed into server and storage backplanes, hot-pluggable drive bays and line cards, telecom and network switch chassis, industrial rack systems, and any application where modules must be replaced without powering down. The 2.5V to 18V range covers the common 3.3V, 5V, and 12V backplane rails used in that equipment.
