BDR6125

Bardeen Micro · Brushed DC Motor Drivers · SOP-8

BDR6125 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 Input signal 1 (BI) controls the H-bridge; it must stay low or high-impedance until VCC has been applied for 3 ms, input high is at least 2.2 V, input low is at most 0.7 V, and the input frequency must not exceed 30 kHz.
2 FI input Input signal 2 (FI) controls the H-bridge; it must stay low or high-impedance until VCC has been applied for 3 ms, input high is at least 2.2 V, input low is at most 0.7 V, and the input frequency must not exceed 30 kHz.
3 GND power_in Ground reference for the device.
4 VCC power_in Power supply input, operating range 3 V to 10 V with an absolute maximum of 12 V; place the VCC input capacitor close to this pin.
5 FO output Control output 1 of the H-bridge, rated for a recommended continuous output current of 0 to 3.0 A (absolute maximum output continuous current 3.5 A).
6 FO output Control output 1 of the H-bridge (same net as pin 5), rated for a recommended continuous output current of 0 to 3.0 A (absolute maximum output continuous current 3.5 A).
7 BO output Control output 2 of the H-bridge, rated for a recommended continuous output current of 0 to 3.0 A (absolute maximum output continuous current 3.5 A).
8 BO output Control output 2 of the H-bridge (same net as pin 7), rated for a recommended continuous output current of 0 to 3.0 A (absolute maximum output continuous current 3.5 A).
