Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD | power_in | Unregulated IC supply input, recommended 3 V to 20 V (VDD-VSS) with absolute maximum 30 V; a series resistor limits current and a capacitor to ground filters noise. |+| 2 | V4 | input | Sense input for the positive voltage of the fourth (top) cell in the stack, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input. |+| 3 | V3 | input | Sense input for the positive voltage of the third cell from the bottom, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input. |+| 4 | V2 | input | Sense input for the positive voltage of the second cell from the bottom, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input. |+| 5 | V1 | input | Sense input for the positive voltage of the bottom cell in the stack, with recommended input range 0 V to 5 V and absolute maximum of 30 V; requires a series RC filter at the input. |+| 6 | VSS | power_in | IC ground, connected to the negative terminal of the bottom cell; absolute maximum rating −0.3 V to 30 V relative to VSS for the other pins. |+| 7 | CD | output | External delay capacitor connection that sets the overvoltage delay tCD = K × CCD (K = 10 to 20 s/µF, so 0.1 µF gives 1 s to 2 s); shorting CD to VSS enables the customer test mode with delay of 170 ms maximum. |+| 8 | OUT | output | Overvoltage fault signal output, factory-set as CMOS active-high or open-drain active-low; the open-drain version requires an external pull-up resistor and absolute maximum is 30 V to VSS. |+| 9 | PowerPAD | power_in | Exposed thermal pad that TI recommends connecting to VSS on the PCB and that must be soldered to the board for 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: `BQ294701DSGR`+- Footprint: `Package_SON:WSON-8-1EP_2x2mm_P0.5mm_EP0.9x1.6mm`+- 3D model: WSON-8-EP(2x2) (KiCad packages3D, STEP)+- 3D model files: `bq294701dsgr-etched.step` / `bq294701dsgr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bq294701dsgr.step` / `bq294701dsgr.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 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
