MAX809STRG

onsemi · Supervisor and Reset ICs · SOT-23

MAX809STRG from onsemi, 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 for the supervisor. Connect to system ground.
2 RESET output Active-low reset output (MAX809). RESET is driven low while VCC is below the 2.93 V (typ) reset threshold and remains low for the reset timeout period (tRP) after VCC rises above the threshold. CMOS push-pull output; VOL <= 0.3 V at ISINK up to 3.2 mA, VOH >= 0.8*VCC.
3 VCC power_in Supply voltage input and monitored rail. Operating range 1.0 V to 5.5 V (1.2 V to 5.5 V over -40 to +105 C). Absolute maximum 6.0 V. This pin is the sensed voltage compared against the internal factory-trimmed reset threshold.

CAD (KiCad official)

  • Symbol: MAX809STRG
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: max809strg-etched.step / max809strg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max809strg.step / max809strg.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
max809strg.step 59 KB You want the bare part, or you mark your own boards.
max809strg-etched.step 2.0 MB You want the part with MAX809STRG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 479 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: onsemi datasheet (13 pp, sha256 9b4684a2978aec65, 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).
