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 | OB | output | Output B. Bi-directional relay coil driver output B. Connects to one terminal of the magnetic latching relay coil; high-impedance when both inputs are equal, driven high/low per the logic table for forward/reverse coil energization. |+| 2 | GND | power_in | Ground reference for the device. Connect to system ground / return of the input supply (VIN). |+| 3 | A | input | Input A. Logic control input; high-level threshold Vth=3V (typ. at Vin=12V), equivalent input resistance ~500 kOhm. Recommended drive pulse width 100 ms. Combined with Input B per the logic table to select forward drive / backward drive / hold. |+| 4 | OA | output | Output A. Bi-directional relay coil driver output A. Connects to the opposite terminal of the magnetic latching relay coil from OB; high-impedance when both inputs are equal, driven high/low per the logic table for forward/reverse coil energization. |+| 5 | VIN | power_in | Supply input voltage. Operating range 5 V to 36 V (40 V absolute max). Quiescent current typically <1 uA. A current-limiting resistor Rs may be inserted in series when Vin > 20V. |+| 6 | B | input | Input B. Logic control input; high-level threshold Vth=3V (typ. at Vin=12V), equivalent input resistance ~500 kOhm. Recommended drive pulse width 100 ms. Combined with Input A per the logic table to select forward drive / backward drive / hold. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-6 |+| Category | Motor Driver ICs |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `BL8023DCB6TR`++## CAD (KiCad official)++- Symbol: `BL8023DCB6TR`+- 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:** [BL Shanghai Belling datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588906620110061568) (5 pp, sha256 `d74263adf01657a7`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
