CN301

ShangHai Consonance Elec · Battery Management · SOT-23-5

CN301 from ShangHai Consonance Elec, in a SOT-23-5. 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 Power supply ground (0V reference).
2 VCC power_in Positive power supply input. Operating range 1.9V to 6V (abs max 6.5V). Typical supply current 1.8µA at VCC=3V.
3 LBO output Battery voltage detection CMOS output. Goes high (VCC-0.4V typ) 60ms after LBI rises above the rising threshold (1.22V typ); goes low immediately (~20µs) when LBI falls below the falling threshold (1.14V typ). Sinks up to 6mA / sources up to 5mA at VCC=5V.
4 LBI input Battery voltage detection input. Typically connected to an external resistor divider from the battery. Bias current ±100nA max; thresholds are 1.22V rising / 1.14V falling (typ, ±2%).
5 NC unconnected No connection. Leave floating or tie as convenient for routing.

CAD (KiCad official)

  • Symbol: CN301
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: cn301-etched.step / cn301-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cn301.step / cn301.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
cn301.step 85 KB You want the bare part, or you mark your own boards.
cn301-etched.step 1.2 MB You want the part with CN301 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 293 faces against 102 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:
