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 | VG | power_out | Internal linear regulator output that powers the internal gate-driver circuitry. Requires a 100nF decoupling capacitor between VG and VCC. |+| 2 | GND | power_in | Ground. Return for input supply and battery negative terminal. |+| 3 | CHRG | output | Charge status indication, open-drain output (active low). Internal transistor pulls low during charging; high-impedance otherwise. Typical pull-down current ~12mA at V_CHRG=1V; leakage <1uA at 30V. |+| 4 | DONE | output | Charge-complete indication, open-drain output (active low). Internal transistor pulls low when charging has finished; high-impedance otherwise. Typical pull-down current ~12mA at V_DONE=1V. |+| 5 | COM | passive | Loop compensation input. Connect a series 120Ω resistor and 220nF capacitor from COM to GND. Absolute-max voltage -0.3V to 6.5V. |+| 6 | FB | input | Battery-voltage feedback input. Senses the positive battery terminal to regulate the 12.6V CV setpoint. An optional resistor Rx between FB and BAT raises V_REG (V_REG = 12.6 + 8.996e-6 × Rx). |+| 7 | BAT | input | Battery positive connection and negative side of current-sense resistor. Connects to the battery pack '+' terminal; together with CSP it measures the voltage across Rcs (120mV typical) to regulate charge current. |+| 8 | CSP | input | Positive side of the charge-current sense input. Measures the voltage across Rcs between CSP and BAT (Ich = 120mV / Rcs) for current-mode regulation. |+| 9 | VCC | power_in | External input power positive terminal and internal-circuit supply (6.6V to 30V). Requires a bypass/decoupling capacitor from VCC to GND. |+| 10 | DRV | output | Gate-driver output for the external P-channel MOSFET switch. VCC-V_DRV swings ~6.3V low / 60mV high; rise/fall ~40ns into 2nF gate load. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SSOP-10-150mil |+| Category | PMIC |+| Pins | 10 |++## Ordering variants++- `CN3763`++## CAD (KiCad official)++- Symbol: `CN3763`+- Footprint: `Package_SO:SSOP-10_3.9x4.9mm_P1.00mm`+- 3D model: SSOP-10-150mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ShangHai Consonance Elec datasheet](docs/cn3763-datasheet.pdf) (11 pp, sha256 `a1f453e0039d36b1`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
