Bardeen Micro · Brushed DC Motor Drivers · DFN-8(2x2)

BDR6122F from Bardeen Micro, in a DFN-8(2x2). 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 VM power_in Motor power supply, specified 0 to 12 V recommended with an absolute maximum of 13 V, and should be decoupled to GND with low-ESR ceramic capacitance such as 0.1 uF placed close to the pin.
2 OUT1 output H-bridge output 1, driving the DC motor or inductive load between OUT1 and OUT2.
3 OUT2 output H-bridge output 2, driving the DC motor or inductive load between OUT1 and OUT2.
4 GND power_in Ground reference for the device, to be connected with thick traces to the decoupling capacitor returns.
5 IN2 input Logic input 2 for PWM control of OUT2 (IN-IN control mode), with an internal 100 kΩ pull-down and a recommended logic input voltage range of 0 to 6 V.
6 IN1 input Logic input 1 for PWM control of OUT1 (IN-IN control mode), with an internal 100 kΩ pull-down and a recommended logic input voltage range of 0 to 6 V.
7 nSLEEP input Sleep mode input: driving it low puts the device into sleep mode with the H-bridge turned off, and it has an internal 100 kΩ pull-down.
8 VCC power_in Logic supply, specified 1.8 to 6 V with an absolute maximum of 6.5 V, and includes undervoltage lockout that disables the bridge when VCC falls below 1.7 V.
