The Pololu high-power motor driver is a discrete MOSFET H-bridge designed to drive large DC brushed motors. The H-bridge is made up of one N-channel MOSFET per leg, and most of the board’s performance is determined by these MOSFETs (the rest of the board contains the circuitry to take user inputs and control the MOSFETs). The MOSFET datasheet is available under the “Resources” tab. The board has an absolute maximum voltage rating of 50 V; 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 44 V.

• Motor channels: 1
• Minimum operating voltage: 5.5 V
• Maximum operating voltage: 50 V
• Continuous output current per channel: 20 A2
• Current sense: 0.066 V/A3
• Maximum PWM frequency: 40 kHz4
• Maximum logic voltage: 5.5 V
• MOSFET on-resistance (max per leg): 4.8 mΩ
• Reverse voltage protection?: N

• Size: 1.8" x 1.2"
• Weight: 7 g

Note: Battery voltages can be much higher than nominal voltages when they are charged, so the maximum battery voltage we recommend is 36 V unless appropriate measures are taken to limit the peak voltage.
