BDR6120S from Bardeen Micro, in a SOT23-6. 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 | OUTB | output | Reverse-direction motor driver output (反转输出); the datasheet gives output current limits of 2.5 A peak and 1.0 A continuous, and a typical on-resistance RON of 0.55 Ω (0.70 Ω max) at VCC = 7.5 V and Io = ±400 mA. |
| 2 | GND | power_in | Ground terminal (接地端) for the device. |
| 3 | INB | input | Reverse-direction logic/PWM input (反转输入); control input voltage range is 0 to VCC, with VIH minimum 2.0 V, VIL maximum 0.8 V, and an internal pull-down resistor of typically 1.3 MΩ. |
| 4 | INA | input | Forward-direction logic/PWM input (正转输入); control input voltage range is 0 to VCC, with VIH minimum 2.0 V, VIL maximum 0.8 V, and an internal pull-down resistor of typically 1.3 MΩ. |
| 5 | VDD | power_in | Power supply pin (电源端); the datasheet specifies an operating range of 2.2 V to 7.5 V, with an absolute maximum supply voltage VCC of 7.5 V. |
| 6 | OUTA | output | Forward-direction motor driver output (正转输出); the datasheet gives output current limits of 2.5 A peak and 1.0 A continuous, and a typical on-resistance RON of 0.55 Ω (0.70 Ω max) at VCC = 7.5 V and Io = ±400 mA. |
