stmps2141str.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 -> 5 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

STMPS2141STR

STMicroelectronics · Analog Switches, Multiplexers · SOT-23-5

STMPS2141STR from STMicroelectronics, in a SOT-23-5. 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 OUT power_out Switched high-side power output. Delivers up to 500 mA continuous from IN through the internal 90 mΩ N-channel MOSFET. Current-limited to a safe level under overload or short-circuit and shut off on thermal trip.
2 GND power_in Device ground reference for the control logic and internal references.
3 FAULT output Open-drain fault indicator, active low. Asserts on overcurrent, short-circuit, thermal shutdown, or reverse-voltage conditions after the internal fault-blanking delay. Requires an external pull-up resistor.
4 EN input Enable input for the power switch. CMOS/TTL compatible. On the STMPS2141 the enable is ACTIVE LOW: drive low to turn the switch ON, drive high to turn it OFF.
5 IN power_in Input supply and drain of the internal high-side MOSFET. Operating range 2.7 V to 5.5 V. Bypass with a local ceramic capacitor to GND.

CAD (KiCad official)

  • Symbol: STMPS2141STR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: stmps2141str-etched.step / stmps2141str-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stmps2141str.step / stmps2141str.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
stmps2141str.step 85 KB You want the bare part, or you mark your own boards.
stmps2141str-etched.step 2.1 MB You want the part with STMPS2141STR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 faces against 102 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (37 pp, sha256 700138497f100d55, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
