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 | V- | input | Current sense input (BATT-) and charger-detection pin. Monitors the voltage across the internal charge/discharge MOSFETs for overcurrent (VOI1 ~150 mV, VOI2 ~1.0 V) and charger-attach detection (VCHA ~-0.5 V). |+| 2 | S1 | passive | Source of the internal charge-control MOSFET; connects to the pack negative terminal (charge path). Carries the full pack current, so this trace must be as short/wide as possible. |+| 3 | S2 | passive | Source of the internal discharge-control MOSFET; must be externally tied to VSS. Provides the return path for discharge current. |+| 4 | D | passive | Common drain of the internal charge and discharge control MOSFETs (back-to-back FET configuration). Handles the full pack current. |+| 5 | VDD | power_in | Positive supply input, connected through R1 (~100 Ω) to the cell positive terminal with a 0.1 uF (104P) decoupling cap to VSS. Operating range 1.5 V to 10 V (abs max VSS+12 V); typical IDD 3.0 uA at VDD=3.9 V. |+| 6 | VSS | power_in | Ground / negative supply - connects to the cell negative terminal. Reference for all internal voltage detection thresholds. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen Fuman |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `DW07D`++## CAD (KiCad official)++- Symbol: `DW07D`+- 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:** [Shenzhen Fuman datasheet](docs/dw07d-datasheet.pdf) (6 pp, sha256 `9777a1b0aaa14e9d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
