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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `CN302`++## CAD (KiCad official)++- Symbol: `CN302`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ShangHai Consonance Elec datasheet](docs/cn302-datasheet.pdf) (8 pp, sha256 `876047edcdfca1b7`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
