LM2901PWR

Texas Instruments · Comparators · TSSOP-14

LM2901PWR from Texas Instruments, in a TSSOP-14. 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 1OUT output Open-collector output of comparator 1. Requires an external pull-up resistor to VCC (or another positive rail up to 36 V). Sinks up to ~16 mA typical.
2 2OUT output Open-collector output of comparator 2. Requires an external pull-up resistor to VCC or another positive rail up to 36 V.
3 VCC power_in Positive supply. Single-supply operation 2 V to 36 V, or split-supply ±1 V to ±18 V. Bypass locally with a 0.1 µF ceramic capacitor.
4 2IN- input Inverting input of comparator 2. Common-mode range includes ground; VICR from 0 V to VCC−1.5 V.
5 2IN+ input Non-inverting input of comparator 2. Common-mode range includes ground.
6 1IN- input Inverting input of comparator 1. Common-mode range includes ground.
7 1IN+ input Non-inverting input of comparator 1. Common-mode range includes ground.
8 3IN+ input Non-inverting input of comparator 3. Common-mode range includes ground.
9 3IN- input Inverting input of comparator 3. Common-mode range includes ground.
10 4IN+ input Non-inverting input of comparator 4. Common-mode range includes ground.
11 4IN- input Inverting input of comparator 4. Common-mode range includes ground.
12 GND power_in Ground / negative supply. In single-supply operation tie to system ground; in split-supply tie to V−.
13 4OUT output Open-collector output of comparator 4. Requires an external pull-up resistor to VCC or another positive rail up to 36 V.
14 3OUT output Open-collector output of comparator 3. Requires an external pull-up resistor to VCC or another positive rail up to 36 V.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: LM2901PWR
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: lm2901pwr-etched.step / lm2901pwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2901pwr.step / lm2901pwr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2901pwr.step 194 KB You want the bare part, or you mark your own boards.
lm2901pwr-etched.step 2.2 MB You want the part with LM2901PWR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 547 faces against 237 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: Texas Instruments datasheet (53 pp, sha256 97e6781f0239a05e, 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).
