Pololu H2 High-Power Motor Driver 36v11 CS
This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3″ × 0.8″ board supports a wide 5 V to 60 V voltage range and is efficient enough to deliver a continuous 11 A without a heat sink. Additional features include reverse-voltage protection and an on-board current sensor that provides a direct measurement of the motor current.

- 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. However, when using high duty cyles below 100%, note that minimum off time requirements must be respected to prevent a spurious latched fault from being triggered. See the “Minimum off time” section on the product page for more information.
