Pololu G2 High Power Motor Driver 21A, 6.5V-40V

• Pololu G2 High Power Motor Driver 21A
• Controls one high-power DC brushed motor
• Output current: 21 A continuous
• Inputs compatible with 1.8 V, 3.3 V, and 5 V logic
• Operating voltage: 6.5 V to 40 V

Please note: 40 V Absolute maximum; higher voltages can permanently destroy the motor driver. The recommended maximum is approximately 34 V, which leaves a safety margin for ripple voltage on the supply line.

The Pololu G2 High Power Motor Driver 21A, 6.5V-40V enables bidirectional control of one high-power DC brushed motor. The small 1.3 x 0.8 inch board supports a wide 6.5 V to 40 V voltage range and is efficient enough to deliver a continuous 21 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.

It 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.
