New product: G2 High-Power Motor Driver 24v13

We are excited to announce the release of the Pololu G2 High-Power Motor Driver 24v13. Like our original high-power motor drivers, this board is a discrete MOSFET H-bridge that is designed to drive large DC brushed motors. As the first of our second-generation high-power motor drivers, the 24v13 can supply a motor with a continuous current as high as 13 A at voltages between 6.5 V and 40 V (absolute maximum).

The G2 driver is designed to be a near drop-in replacement for its predecessor, with an identical form factor and a similar pinout, but it offers a number of new features and improvements over the older version. Reverse-voltage protection on the power supply inputs helps prevent instant destruction if a battery is connected backwards, while basic current sensing and limiting functionality help the driver handle large loads more gracefully. The G2 driver is also compatible with systems running at 3.3 V (and lower), unlike our original high-power motor drivers.

To learn more about the motor driver’s features and capabilities, see its product page.


Dear, question: was this product offered also on black friday? Or... where can I see your black friday offers? Thx
Hello, Matija.

All of our High-Power Motor Drivers, including this one, were discounted during our Black Friday sale. The sale is now over, and the offers are no longer available.

I would like to know that is it possible to use this driver at 100kHz, locked anti-phase mode, without heat sink?

The G2 High-Power Motor Driver 24v13 can be used at 100kHz with locked-antiphase control. Whether a heat sink is needed for your application will depend on your motor and the load you put on it. However, the specifications we give on the driver's product page are for operation at ambient room temperature without a heat sink.

The phrase from description about current chopping "once the motor drive current reaches a set threshold, the driver goes into brake mode (slow decay) for a brief time before applying power to drive the motor again."

How long is "a brief time"? is it a little microsecond?
The driver will go into brake mode for about 25us once the current chopping threshold is reached. We have updated the description on the product pages for our Pololu G2 High-Power Motor Drivers to include that information as well.

where do I find schematic and BOM for G2 High-Power Motor Driver 24v13?
Hi, Nils J.

We do not release the schematic for that driver. Is there some other specific information about the driver you are looking for?

I see, that is a pity. Can I get the component list (BOM)? I need to see the datasheets before I buy the board.
Sorry, we do not release that.


When VIN is turned on to 6.5V (consumes 0.038A) I see also VM go from initial setting 2.0V rise to 5.8V. Is that normal?

Hi, tarball.

A quiescent current of 38mA seems a little high, but it is probably fine. I do not understand what the other part of your question is asking. If you are having trouble with your G2 High-Power Motor Driver or are looking for more in-depth specifications, I suggest posting on our forum, which is a better platform for those things.
