The Texas Instruments LM73100RPWR is a power distribution switch and load driver that operates across a 2.7V to 23V supply range and is rated for 5.5A. A power distribution switch sits between a supply rail and a downstream load, providing controlled turn-on, inrush limiting, and a means to isolate a fault without dropping the whole rail. The LM73100RPWR comes in a 10-pin VQFN package measuring 2mm by 2mm with a 1mm height, and is rated from -40C to +125C with a 125C maximum junction temperature.

Wide-input power distribution switches are used to protect and sequence downstream rails on boards fed from 5V, 12V, or 24V supplies: hot-swap and plug-in module protection, inrush control on large bulk capacitors, USB and peripheral port power gating, motor and solenoid drive enables, and rail sequencing on multi-supply systems. The 2mm by 2mm VQFN footprint suits designs where board area is the binding constraint. Buyers are typically power and embedded hardware engineers, industrial and networking equipment OEMs, and EMS providers sourcing to a released BOM.
