SSP809C308NR

Shanghai Siproin Microelectronics · Supervisor and Reset ICs · SOT-23

SSP809C308NR from Shanghai Siproin Microelectronics, 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 (Vss). Connect to system ground.
2 VIN power_in Input supply / monitored voltage pin. Operating range 1.2V to 7.5V; absolute maximum 8.0V. This is the voltage that the detector compares against the internal VDET threshold (3.08V typ for the C308 variant).
3 Vout/Reset output CMOS push-pull reset output. Driven low when VIN falls below VDET (3.08V typ), and held low for a 200ms active timeout period after VIN recovers above threshold. No external pull-up required for the 'C' (CMOS) variant.

Two STEP files. Same geometry, different body top:

File Size Use it when
ssp809c308nr.step 59 KB You want the bare part, or you mark your own boards.
ssp809c308nr-etched.step 2.9 MB You want the part with SSP809C308NR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 664 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: Shanghai Siproin Microelectronics datasheet (7 pp, sha256 0ca8af4133e9fda5, 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).
