This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The compact 1.8×1.2-inch board supports a wide 5.5 to 30 V voltage range and is efficient enough to deliver a continuous 25 A without a heat sink. This version outputs an analog voltage proportional to the motor current, and an extra control input allows for coasting in addition to the driving and braking offered by the other Pololu high-power motor drivers.

Some discrete MOSFET based H-bridges are unable to handle a continuously high PWM signal (100% duty cycle). This has to do with bootstrap capacitors not having enough time to charge. Does this bridge allow 100% duty cycle PWM input?
Yes. The design has an extra charge pump that allows the high-side MOSFETs to stay on indefinitely for 100% duty cycle operation.
