Pololu G2 High-Power Motor Driver 24v13 (BACKORDER)

Description

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 6.5 V to 40 V voltage range and is efficient enough to deliver a continuous 13 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 DC brushed 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. The motor and motor power connections are on one side of the board, and the control connections (1.8 V to 5 V logic) are on the other side. The motor supply should be capable of supplying high current. There are two options for making the high-power connections (VIN, OUTA, OUTB, GND): large holes spaced 5 mm apart, which are compatible with the included terminal blocks, and pairs of 0.1?-spaced holes that can be used with perfboards, breadboards , and 0.1? connectors .
