BDR6127 from Bardeen Micro, in a SOP-8. 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 | BI | input | Reverse-direction logic input that, together with FI, selects forward, reverse, brake or stop per the truth table; recommended input range is -0.3 V to 6.0 V, with VINH at least 2.2 V and VINL at most 0.7 V. |
| 2 | FI | input | Forward-direction logic input that, together with BI, selects forward, reverse, brake or stop; recommended input range is -0.3 V to 6.0 V, logic input frequency must not exceed 50 kHz, and BI/FI must stay low or high-impedance until VCC has been up for 3 ms. |
| 3 | GND | power_in | Power ground; all datasheet voltage values are referenced to this terminal. |
| 4 | VCC | power_in | Motor driver supply, operating range 3.0 V to 18.0 V (absolute maximum 20 V, supply slope at most 1 V/µs), with undervoltage lockout at 1.9 V to 2.8 V on rising VCC. |
| 5 | FO | output | Forward H-bridge output driving the motor, high in forward mode (FI=H, BI=L) and open in stop mode; maximum continuous current 5.0 A and peak 8.0 A when VCC > 6 V. |
| 6 | FO | output | Forward H-bridge output driving the motor, high in forward mode (FI=H, BI=L) and open in stop mode; maximum continuous current 5.0 A and peak 8.0 A when VCC > 6 V. |
| 7 | BO | output | Reverse H-bridge output driving the motor, high in reverse mode (BI=H, FI=L) and open in stop mode; maximum continuous current 5.0 A and peak 8.0 A when VCC > 6 V. |
| 8 | BO | output | Reverse H-bridge output driving the motor, high in reverse mode (BI=H, FI=L) and open in stop mode; maximum continuous current 5.0 A and peak 8.0 A when VCC > 6 V. |
