Pololu High-Power Motor Driver 24v12
This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The little 1.3×0.8-inch board supports a wide 5.5 to 40 V voltage range and is efficient enough to deliver a continuous 12 A without a heat sink.

- Without any connectors or through-hole capacitors.
- Typical results with 100% duty cycle at room temperature. Continuous current can be as high as 18 A if the MOSFETs are kept cool with air flow or a heat sink.
- Higher frequencies are possible, but duty cycle will be limited by dead time of approximately 3 μs per cycle.
