This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 33mm × 20mm board supports a wide 6.5 V to 30 V voltage range and is efficient enough to deliver a continuous 17 A without a heat sink. Additional features of this second-generation (G2) driver include reverse-voltage protection along with basic current sensing and current limiting functionality.

The Pololu G2 high-power motor driver is a discrete MOSFET H-bridge designed to drive large brushed DC motors. The H-bridge is made up of one N-channel MOSFET per leg; the rest of the board contains the circuitry to take user inputs and control the MOSFETs. The absolute maximum voltage for this motor driver is 30 V, and higher voltages can permanently destroy the motor driver. Under normal operating conditions, ripple voltage on the supply line can raise the maximum voltage to more than the average or intended voltage, so a safe maximum voltage is approximately 24 V.

Note: Battery voltages can be much higher than nominal voltages when they are charged, so the maximum nominal battery voltage we recommend is 18 V (and use with 24 V batteries is not recommended) unless appropriate measures are taken to limit the peak voltage.

Features:
• Operating voltage: 6.5 V to 30 V (absolute maximum)
• Output current: 17 A continuous
• Inputs compatible with 1.8 V, 3.3 V, and 5 V logic
• PWM operation up to 100 kHz
• Current sense output proportional to motor current (approx. 20 mV/A; only active while H-bridge is driving)
• Active current limiting (chopping) with default threshold of 40 A (can be adjusted lower)
• Reverse-voltage protection
• Undervoltage shutdown
• Short circuit protection
