At full load the 80 mOhm Rds(on) produces a 40 mV drop and about 20 mW of self-heating — well within the 8-SOIC package's thermal capability at 25°C ambient. ## Fault protection reduces external BOM Fixed current limiting (typically 0.75 A to 1.25 A trip range) and over-temperature shutdown eliminate the need for a separate PTC fuse or current-sense resistor. The open-drain Status Flag output asserts low when the switch is in current-limit or thermal-shutdown — a direct interrupt to the system controller. UVLO holds the switch off until the input bus reaches about 2.4 V, preventing brownout glitches. The 8-SOIC package ships in Tape & Reel (TR), compatible with standard pick-and-place lines.","metaTitle":"TPS2051DR Power Distribution Switch, 500 mA, 80 mOhm, 8-SOIC","metaDescription":"Texas Instruments TPS2051DR high-side power switch: 500 mA output, 80 mOhm Rds(on), fault protection, -40°C to 125°C.
