ME2803A33M3G

MICRONE · Supervisor and Reset ICs · SOT-23

ME2803A33M3G from MICRONE, in a SOT-23. 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 VOUT output CMOS push-pull detector output. Equals VIN when VIN is above the detect-release threshold (+VDET); pulled to GND when VIN falls below -VDET (nominally 3.3V for A33). IOUT abs max 50 mA; typical P-ch source 3.4 mA at VDS=0.5V, VIN=7V; typical N-ch sink 0.14 mA at VDS=0.5V, VIN=0.7V.
2 GND power_in Ground reference for the detector and CMOS output stage.
3 VIN power_in Monitored input voltage and device supply. Operating range 0.7V to 7V (absolute max 8V). Typical supply current ~0.7 µA at VIN=3.5V. Datasheet recommends VIN rise/fall times of several µs/V for stable operation.

  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: me2803a33m3g-etched.step / me2803a33m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me2803a33m3g.step / me2803a33m3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me2803a33m3g.step 59 KB You want the bare part, or you mark your own boards.
me2803a33m3g-etched.step 2.6 MB You want the part with ME2803A33M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 614 faces against 69 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: MICRONE datasheet (12 pp, sha256 aaae3b5e8fdc0db2, retrieved 2026-08-17, tier: lcsc)
  • 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).
