BDR6121H 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 | NC | unconnected | No-connect (empty) pin, not internally connected and not to be used. |
| 2 | INA | input | Forward (positive-rotation) PWM control input; control input range is 0 to VCC, with logic-high at 2.0 V minimum and logic-low at 0.8 V maximum, and an internal 1.5 MΩ pull-down. |
| 3 | INB | input | Reverse PWM control input; control input range is 0 to VCC, with logic-high at 2.0 V minimum and logic-low at 0.8 V maximum, and an internal 1.5 MΩ pull-down. |
| 4 | VDD | power_in | Supply pin; operating range is 2.2 V to 7.5 V (absolute maximum VCC 7.5 V). |
| 5 | OUTB | output | Reverse motor output; peak output current 3 A and maximum continuous output current 1.55 A, with RON of 0.45 Ω typical at VCC = 7.5 V and Io = ±400 mA. |
| 6 | NC | unconnected | No-connect (empty) pin, not internally connected and not to be used. |
| 7 | PGND | power_in | Ground pin for the device. |
| 8 | OUTA | output | Forward motor output; peak output current 3 A and maximum continuous output current 1.55 A, with RON of 0.45 Ω typical at VCC = 7.5 V and Io = ±400 mA. |
