MAX809M

TECH PUBLIC · Supervisor and Reset ICs · SOT-23

MAX809M from TECH PUBLIC, 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 GND power_in Ground reference pin. Connect to the system ground plane.
2 RESET output Active-low reset output (push-pull). RESET is driven low when VDD falls below the reset threshold (4.38 V typ for the 'M' suffix) and returns high at least 140 ms after VDD rises back above the threshold. VOL <= 0.3 V sinking up to 5 mA at VDD=4V; VOH >= VDD-0.4 V sourcing 2 mA at VDD=4V.
3 VDD power_in Chip supply and monitored voltage input. Operating range 1.0 V to 5.5 V; typical IDD 10 uA at 3.0 V. Place a decoupling capacitor as close as possible to this pin to filter supply glitches.

Ordering variants

Same part, different packaging or reel option.

  • MAX809M

CAD (KiCad official)

  • Symbol: MAX809M
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: max809m-etched.step / max809m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max809m.step / max809m.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
max809m.step 59 KB You want the bare part, or you mark your own boards.
max809m-etched.step 1.4 MB You want the part with MAX809M already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 344 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: TECH PUBLIC datasheet (7 pp, sha256 68b511dbe976a4d5, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
