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 | BST | passive | Bootstrap supply for the floating high-side power NMOS driver. Connect a bypass capacitor between BST and LX for bootstrap operation. Max BST-to-GND 50V; max BST-to-LX 7V. |+| 2 | GND | power_in | Ground return. Should be connected as close as possible to the output capacitor ground to avoid the high-current switching path. |+| 3 | FB | input | Voltage feedback pin; error-amp input. The DC/DC regulates FB to 0.75V (±1.5% at 25°C). Set output voltage with an external resistor divider from VOUT to FB. Max FB voltage 7V. |+| 4 | EN | input | Enable input. DC/DC starts when EN ≥ 2.0V; shuts down when EN is open or ≤ 0.8V. Internal pull-down of about 550kΩ to GND. Max EN voltage 45V. |+| 5 | VCC | power_in | Input supply pin, 6V to 42V operating range (45V absolute max). Should be bypassed with a capacitor located as close to the pin as possible. |+| 6 | LX | output | Power NMOS switch node output. Connect to the Schottky freewheeling diode and inductor as close to the pin as possible. Max LX voltage 45V; typical switch current limit 1.2A. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `BD9G101G-TRTR`++## CAD (KiCad official)++- Symbol: `BD9G101G-TR`+- 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:** [ROHM datasheet](docs/bd9g101g-tr-datasheet.pdf) (26 pp, sha256 `8a1aa401940eac2d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
