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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## CAD (KiCad official)++- Symbol: `CN301`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ShangHai Consonance Elec datasheet](docs/cn301-datasheet.pdf) (8 pp, sha256 `e53d85895b1992c6`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
