SSP61CN3502MR

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

SSP61CN3502MR 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 VOUT output Detector output. NMOS open-drain configuration (per the 'N' order-code option): pulled low (VSS) when VIN <= VDET(-), and high-impedance (Hi-Z) when VIN > VDET(+). Requires an external pull-up (typ. 47 k to 100 k ohms) to the desired logic rail. Output sink current IOL >= 0.5 mA (typ 1 mA) at VOUT=0.2 V with VIN=2 V.
2 GND power_in Ground / VSS reference. Connect to system 0 V. Also serves as the low-side of the internal NMOS open-drain output transistor.
3 VIN power_in Supply / sense voltage input. Operating voltage 0.7 V to 10 V; absolute maximum 8.0 V (VIN -0.3 to +8.0 V). Quiescent supply current is only ~0.9 uA typ at 3 V (max 3.0 uA).

CAD (KiCad official)

  • Symbol: SSP61CN3502MR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ssp61cn3502mr-etched.step / ssp61cn3502mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ssp61cn3502mr.step / ssp61cn3502mr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ssp61cn3502mr.step 59 KB You want the bare part, or you mark your own boards.
ssp61cn3502mr-etched.step 2.6 MB You want the part with SSP61CN3502MR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 611 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:
