ME2808A50M3G

MICRONE · Supervisor and Reset ICs · SOT-23

ME2808A50M3G 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 Detector output. NMOS open-drain, active-low: normally high (via external pull-up) and pulled low when VIN drops below the 5.0 V detection threshold (VDET). Requires an external pull-up resistor to the desired logic rail. Output sink current typically 2.5 mA at VOUT=0.3 V for the 5.0 V variant.
2 GND power_in Ground / negative supply reference for the device. Common return for the input voltage divider, comparator, reference and output NMOS source.
3 VIN power_in Input supply and voltage being monitored. Absolute max 18 V; operating range 1.5 V to 18 V. Also acts as the sensed rail whose level is compared against the internal 5.0 V threshold.

  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: me2808a50m3g-etched.step / me2808a50m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me2808a50m3g.step / me2808a50m3g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
me2808a50m3g.step 59 KB You want the bare part, or you mark your own boards.
me2808a50m3g-etched.step 2.5 MB You want the part with ME2808A50M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 602 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 373a5eda254f1153, 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).
