The Texas Instruments TPS2557QDRBRQ1 is a single-channel high-side USB power distribution switch supplied in an 8-pin VSON package. It operates from a 2.5 V to 6.5 V supply and supports up to 5 A of output current, with over-temperature fault protection and a simple on/off enable interface. The TPS2557QDRBRQ1 belongs to the TPS2557-Q1 series and is a surface-mount, lead-free, RoHS-compliant device rated for -40°C to 125°C operation. It ships on tape and reel in 3, 000-piece quantities at MSL 2.

High-side power distribution switches are used to gate and protect power rails that feed USB ports, downstream peripherals, and hot-pluggable connectors, where inrush current and short-circuit events must be contained at the connector. With a 2.5 V to 6.5 V input range and 5 A capability, the TPS2557QDRBRQ1 suits 3.3 V and 5 V rails in automotive infotainment, industrial control, and embedded computing designs. Its -40°C to 125°C rating and TPS2557-Q1 series designation target systems that must operate across an extended temperature range. Typical buyers are hardware design engineers and OEM or EMS procurement teams sourcing protected power-switching front ends.
