tps25221dbvr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 6 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TPS25221DBVR

Texas Instruments · Supervisor and Reset ICs · SOT-23-6

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.

CAD (KiCad official)

  • Symbol: TPS25221DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tps25221dbvr-etched.step / tps25221dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps25221dbvr.step / tps25221dbvr.glb are the bare package body.

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.
