CN302

ShangHai Consonance Elec · Battery Management · SOT-23-6

CN302 from ShangHai Consonance Elec, in a SOT-23-6. 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 FTH input Falling (lower) threshold input. Connect to an external resistor divider tapping the battery voltage. When VFTH falls below the internal 1.211V reference, /LBO goes low and LBO goes high after ~13µs delay. Input leakage ±10nA.
2 GND power_in Power ground (0V reference).
3 LBO output Active-high battery-low detect output, CMOS push-pull. Drives high when VFTH < Vref (battery low) and low when VRTH > Vref (battery OK). VOL ≤ 0.3V at ISINK=3.2mA (VCC=3V); VOH ≥ VCC-0.4V at ISOURCE=3mA.
4 VCC power_in Positive supply input. Operating range 1.9V to 6V; absolute max 6.5V. Typical supply current 9.5µA at VCC=3V.
5 /LBO output Active-low battery-low detect output (complement of LBO), CMOS push-pull. Drives low when VFTH < Vref (battery low) and high when VRTH > Vref (battery OK). VOL ≤ 0.3V at ISINK=3.2mA (VCC=3V); VOH ≥ VCC-0.4V at ISOURCE=3mA.
6 RTH input Rising (upper) threshold input. Connect to an external resistor divider tapping the battery voltage. When VRTH rises above the internal 1.211V reference, /LBO goes high and LBO goes low after ~12µs delay. Input leakage ±10nA.

Ordering variants

Same part, different packaging or reel option.

  • CN302

CAD (KiCad official)

  • Symbol: CN302
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: cn302-etched.step / cn302-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cn302.step / cn302.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
cn302.step 97 KB You want the bare part, or you mark your own boards.
cn302-etched.step 1.3 MB You want the part with CN302 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 325 faces against 117 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 Consonance Elec datasheet (8 pp, sha256 876047edcdfca1b7, 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).
