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 | VDD | power_in | Unregulated IC power input, recommended range 3V to 20V, absolute max 30V; typically filtered with a series resistor and decoupling capacitor to VSS. |+| 2 | V4 | input | Analog sense input for the positive terminal voltage of the fourth (topmost) cell from the bottom of the battery stack, monitored as V4-V3 for overvoltage detection. |+| 3 | V3 | input | Analog sense input for the positive terminal voltage of the third cell from the bottom of the battery stack, monitored as V3-V2 for overvoltage detection. |+| 4 | V2 | input | Analog sense input for the positive terminal voltage of the second cell from the bottom of the battery stack, monitored as V2-V1 for overvoltage detection. |+| 5 | V1 | input | Analog sense input for the positive terminal voltage of the bottommost cell in the battery stack, monitored as V1-VSS for overvoltage detection. |+| 6 | VSS | power_in | Ground reference pin, electrically connected to the IC ground and to the negative terminal of the bottommost cell in the battery pack. |+| 7 | CD | output | Analog output/timing pin for connection of an external capacitor that sets the overvoltage fault delay timer (tCD = K x CCD, K=10 to 20); also includes open/short timeout detection on this pin. |+| 8 | OUT | output | Analog output driver for the overvoltage fault signal; for this active-high CMOS version (BQ294705), OUT is pulled high (toward VDD) when an overvoltage fault is active and driven low (typ. 250-400 mV) when no fault is present. |+| 9 | PowerPAD | power_in | Exposed thermal pad; TI recommends connecting the exposed pad to VSS on the PCB, and it must be soldered to the board for proper thermal and mechanical performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WSON-8-EP(2x2) |+| Category | Power Management (PMIC) |+| Pins | 9 |++## CAD (KiCad official)++- Symbol: `BQ294705DSGR`+- Footprint: `Package_SON:WSON-8-1EP_2x2mm_P0.5mm_EP0.9x1.6mm`+- 3D model: WSON-8-EP(2x2) (KiCad packages3D, STEP)+- 3D model files: `bq294705dsgr-etched.step` / `bq294705dsgr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bq294705dsgr.step` / `bq294705dsgr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/bq2947) (30 pp, sha256 `0bb66de94396f561`, retrieved 2026-09-23, tier: lcsc)+- **Datasheet language:** Chinese.
