TPS25221DBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	IN	power_in	Input voltage and power switch drain. Operating range 2.5 V to 5.5 V. Connect a 0.1 µF or greater ceramic bypass capacitor from IN to GND close to the IC.
2	GND	power_in	Ground connection. Internal thermal path also references GND (thermal pad on WSON variant is connected internally to GND).
3	EN	input	Active-high enable input. Logic high turns the power switch on; logic low turns it off. VIH ≥ 1.7 V, VIL ≤ 0.66 V; absolute range 0 to 5.5 V.
4	FAULT	output	Active-low open-drain fault flag. Asserted low during over-current or over-temperature conditions after the ~8 ms deglitch. Requires an external pull-up (typ. 20 kΩ). Max sink current 25 mA.
5	ILIM	output	Current-limit programming pin. External resistor to GND (20 kΩ to 210 kΩ) sets the current-limit threshold from ~2.72 A down to ~275 mA. ILIM source current limited to 1 mA max.
6	OUT	power_out	Power switch output; connect to load. Delivers up to 2 A continuous. USB applications require ≥120 µF bulk capacitance on downstream ports.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps25221dbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps25221dbvr-etched.step`	2.3 MB	You want the part with `TPS25221DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 560 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
