BL8023FCB6TR from BL Shanghai Belling, in a SOT-23-6. 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. Drives one terminal of the magnetic latching relay coil. High-side/low-side push-pull output that is high-impedance when both inputs are equal (00 or 11). Paired with OA to bi-directionally drive the coil. |
| 2 | GND | power_in | Device ground reference. |
| 3 | A | input | Input A logic control pin. Input high threshold ~2V (Vin=12V); equivalent input resistance ~500kΩ. When A=1, B=0 the relay is driven ON (forward); other combinations produce either reverse drive or high-impedance hold state. |
| 4 | OA | output | Output A. Drives the opposite terminal of the magnetic latching relay coil. Push-pull output paired with OB; high-impedance when inputs A and B are equal. |
| 5 | VIN | power_in | Supply input voltage. Operating range 5V to 36V (absolute max 40V). Quiescent current <1uA typical. |
| 6 | B | input | Input B logic control pin. Input high threshold ~2V; equivalent input resistance ~500kΩ. When B=1, A=0 the relay is driven OFF (reverse); when A=B the outputs are high-impedance (hold). |
