The TPS22918TDBVRQ1 is a single-channel high-side power load switch from Texas Instruments in a 6-pin SOT-23 package, part of the automotive-qualified TPS22918-Q1 series. It operates across a 1V to 5.5V supply and passes up to 2A of output current on one channel. A load switch of this type places a controlled pass element between a supply rail and a downstream load, allowing a host controller to power sections of a board on and off. Texas Instruments lists the TPS22918TDBVRQ1 as active production.

The TPS22918TDBVRQ1 gates power to subsystems that do not need to stay energised, which is how designers cut standby current in battery-powered and automotive electronics. Typical uses are switching supply to sensors, camera and display modules, wireless radios and peripheral rails, and sequencing rails so a processor's supplies come up in the required order. Controlled turn-on also limits inrush current into bulk capacitance, protecting upstream regulators from a rail collapse at start-up. The -40°C to 105°C rating and Q1 series designation point at automotive and harsh-environment use. Buyers are automotive tier suppliers, industrial OEMs and contract manufacturers building power-managed boards.
