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 | DOUT | output | Discharge control output. Connects to the gate (G) of the external discharge-control N-MOSFET Q2. High = Q2 on (discharge enabled); low (VSS level) = Q2 off (discharge cut off) under over-discharge or over-current fault. |+| 2 | VM | input | Charge/discharge current sense input. Connects through a current-limit resistor (typ. 1 kΩ) to the source of the charge-control N-MOSFET Q1, sensing the voltage drop across Q1+Q2. Used to detect charger presence (VCHG ≈ -0.5 V), over-current discharge (VEDI ≈ 0.15 V), and battery short (VSHORT ≈ 1.36 V). |+| 3 | COUT | output | Charge control output. Connects to the gate (G) of the external charge-control N-MOSFET Q1. High = Q1 on (charge enabled); low (VM level) = Q1 off (charge cut off) under over-charge fault. |+| 4 | NC | unconnected | No connect. Leave floating. |+| 5 | VDD | power_in | Positive supply input, connected to the battery positive terminal through a series resistor R1 (typ. 1 kΩ). Absolute max -0.3 V to +10 V; operating 1.5 V to 10 V. Requires a 0.1 µF ceramic decoupling cap to VSS. Typical supply current 2 µA (VDD = 3.9 V), 0.7 µA in low-power mode. |+| 6 | VSS | power_in | Ground / negative supply. Connects to the battery negative terminal. All internal thresholds are referenced to VSS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `DW01-A`+- 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:** [Unknown datasheet](docs/dw01-a-datasheet.pdf) (10 pp, sha256 `6fcfde09264c5e11`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
