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. Drives the gate (G) of the external discharge-control N-MOS Q2. High level ~ VDD-0.2V (IDOUT=10uA), low level ~ 0.2V. |+| 2 | VM | input | Charge/discharge current-sense input. Connects through a current-limit resistor (typ. 1kΩ, R2) to the source (S) of the external charge-control N-MOS Q1, sensing the voltage drop across Q1+Q2 to detect over-current and short-circuit conditions. Internally pulled up to VDD via RVMD (typ. 1.5MΩ) and down to VSS via RVMS (typ. 20kΩ). |+| 3 | COUT | output | Charge control output. Drives the gate (G) of the external charge-control N-MOS Q1. High level ~ VDD-0.2V, internal pull-down to VM ~ 4.0MΩ in protection state. |+| 4 | NC | unconnected | No connection. Leave floating. |+| 5 | VDD | power_in | Power supply (positive battery terminal). Connect to the battery '+' through R1 (recommended 330Ω) and bypass to VSS with a 0.1uF ceramic capacitor (C1). Operating range 1.5V to 6V, absolute max -0.3V to +6V. |+| 6 | VSS | power_in | Ground / negative battery terminal. All voltage thresholds are referenced to VSS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XIN FEI HONG |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `FH3016FDYFDY`++## CAD (KiCad official)++- Symbol: `FH3016FDY`+- 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:** [XIN FEI HONG datasheet](docs/fh3016fdy-datasheet.pdf) (11 pp, sha256 `b4eb49239e5357da`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
