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.

Notes:
- 1
- Without included connectors.
- 2
- Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 48 V, which leaves a safety margin for ripple voltage on the supply line. Not recommended for use with 48V batteries.
- 3
- Typical results with 100% duty cycle at room temperature.
- 4
- When Vcc = 5 V. Sensitivity is proportional to Vcc.
- 5
- Minimum required for operation below 100% duty cycle; shorter off times can trigger spurious short circuit faults.
