The Texas Instruments TPS22810DRVR is an 18 V, 3 A load switch with 79 m Ohm on-resistance, adjustable rise time and adjustable output discharge. It operates from 2.7 V to 18 V with a single channel and one output, and the record lists 120 us rise time, 2 us fall time, 185 us turn-on delay and 3.3 us turn-off delay. TPS22810DRVR is supplied in a 6-pin WSON measuring 2 mm x 2 mm x 0.8 mm, rated -40 C to 105 C with a 150 C maximum junction temperature, and is RoHS compliant.

A load switch gates power to a subsystem under logic control, and the adjustable rise time is the key feature: ramping the output slowly limits inrush current into bulk capacitance so the upstream rail does not sag and trip a supervisor. Adjustable output discharge ensures the downstream rail actually collapses on shutdown rather than floating. Typical uses are power sequencing on multi-rail boards, hot-plug and expansion-slot protection, standby power gating for battery life, and USB and peripheral port power control. Note this part is filed under Gate Drivers in the catalog but functions as an integrated load switch.
