Pololu G2 High-Power Motor Driver 24v13

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 6.5V to 40V voltage range and is efficient enough to deliver a continuous 13A without a heat sink. Driver includes reverse-voltage protection along with basic current sensing and current limiting functionality. Pololu 2992

Description

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 40 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 34 V.

NOTE: Battery voltages can be much higher than nominal voltages when they are charged, so the maximum nominal battery voltage we recommend is 28 V unless appropriate measures are taken to limit the peak voltage.

Features

  • Operating voltage: 6.5 V to 40 V (absolute maximum)
  • Output current: 13 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. 40 mV/A; only active while H-bridge is driving)
  • Active current limiting (chopping) with default threshold of 30 A (can be adjusted lower)
  • Reverse-voltage protection
  • Undervoltage shutdown
  • Short circuit protection
