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 | IN1 | input | Voltage detection input 1. Typically connected to an external resistor divider to sense a voltage. Rising threshold VRTH1 = 1.211V typ, falling threshold VFTH1 = 1.12V typ. Input leakage ±100nA max. |+| 2 | GND | power_in | Power ground reference for the device. |+| 3 | OUT1 | output | Voltage detection output 1. CMOS output - drives high when IN1 exceeds the rising threshold and low when IN1 falls 7.5% below the rising threshold. VOL ≤ 0.3V at ISINK=3.2mA (VCC=3V); VOH ≥ VCC−0.4V at ISOURCE=3mA (VCC=3V). |+| 4 | VCC | power_in | Positive supply input for internal circuitry. Operating range 1.9V to 6V (absolute max 6.5V). Typical IVCC = 11µA at VCC=3V. |+| 5 | OUT2 | output | Voltage detection output 2. CMOS output - drives high when IN2 exceeds the rising threshold and low when IN2 falls 7.5% below the rising threshold. Same drive levels as OUT1. |+| 6 | IN2 | input | Voltage detection input 2. Typically connected to an external resistor divider to sense a voltage. Rising threshold VRTH2 = 1.211V typ, falling threshold VFTH2 = 1.12V typ. Input leakage ±100nA max. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `CN303`++## CAD (KiCad official)++- Symbol: `CN303`+- 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/cn303-datasheet.pdf) (7 pp, sha256 `2bedab7350bdff1a`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
