MAX809L

TECH PUBLIC · Supervisor and Reset ICs · SOT-23

MAX809L 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 return pin. Connect to the system 0 V reference.
2 RESET output Active-low reset output (push-pull). Goes low when VDD falls below the reset threshold (V_RST = 4.63 V typ for L variant) and remains low for at least 140 ms after VDD rises back above V_RST. Output drive: sinks 1.5-5 mA at V_OL ≤ 0.3 V and sources 1.2-2.5 mA at V_OH ≥ VDD−0.4 V depending on VDD.
3 VDD power_in Chip supply and monitored voltage input. Operating range 1.0 V to 5.5 V (abs max 6.0 V). Typical supply current 8 µA at 2 V, 10 µA at 3 V, 14 µA at 5 V. Slew-rate limit 100 V/s.

Ordering variants

Same part, different packaging or reel option.

  • MAX809LL

CAD (KiCad official)

  • Symbol: MAX809L
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: max809l-etched.step / max809l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max809l.step / max809l.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
max809l.step 59 KB You want the bare part, or you mark your own boards.
max809l-etched.step 1.3 MB You want the part with MAX809L already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 333 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 70f9dac69af03bf0, 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).
