cn809t.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

CN809T

ShangHai Consonance Elec · Supervisor and Reset ICs · SOT-23-3

CN809T from ShangHai Consonance Elec, in a SOT-23-3. 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 device.
2 RESET output Active-low CMOS reset output. Driven low when VCC falls below the reset threshold (VRES = 3.08 V typical for the T-suffix). After VCC rises above VRES + VHYST, RESET remains low for at least 140 ms (typ 240 ms) before returning high. Push-pull CMOS output: VOL <= 0.3 V at ISINK = 3.2 mA (VCC = 3 V); VOH >= VCC - 0.4 V at ISRC = 1.2 mA (VCC = 3 V).
3 VCC power_in Positive supply input; this pin is both the device's operating supply and the voltage being monitored. Absolute max 6.0 V; recommended operating range up to 5.5 V. Place a 0.1 µF bypass capacitor close to this pin to improve rejection of short supply glitches.

Same part, different packaging or reel option.

  • CN809T

CAD (KiCad official)

  • Symbol: CN809T
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: cn809t-etched.step / cn809t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cn809t.step / cn809t.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
cn809t.step 59 KB You want the bare part, or you mark your own boards.
cn809t-etched.step 1.3 MB You want the part with CN809T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 320 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.
