    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?

    Hi, Brewster.

    It is generally bad practice to directly connect two voltage sources, so you should implement something to isolate your 12-15V rail from the output of the regulator. Appropriately rated diodes could work for that. Even when the regulator is off, it is not good practice to connect another voltage to the output, and you should definitely not connect more than 5V.

    Hi, Moby.

    We do not disclose what IC is used on this regulator. We will be releasing an adjustable version soon, though stock will initially be limited because of component shortages. Please contact us directly with the details of your requirements (output voltage, quantity you need, when you need them, etc.), and we might be able to get you something sooner than the regular release.

    Hi, Tech.

    In our tests the G2 High-Power Motor Driver 24v21 was able to handle 21A continuously. Those tests were done in open air at room temperature, so you might see a decrease in performance if your driver is enclosed or in a hot environment. We do not expect varied input voltages to have a significant impact on the continuous current the driver can handle. We did not test the driver with heatsinks, but adding a heatsink would probably slightly improve the amount of current it can handle.

    Hi, Chris.

    The product pages for our stepper motor driver carriers cover most of the same information that is in the video on setting the current limit. What specific information do you think is missing from the product pages?

    Hi.

    We do not commit to the exact MOSFETs on these, but the Rds(on) is around 1 mohm for the 18v25 and 2.4 mohms for the 24v21. Keep in mind that there are 3 MOSFETs in the current path because of the reverse protection MOSFET.

    Hi, Manlio.

    Adding capacitors might help. You might find this application note about dealing with motor noise helpful.

    Hi, Aaron.

    We do not release the name of the chip used on those regulators. The power good pin is an indicator of whether the output of the regulator is above 85% or 90% (depending on if the output voltage is falling or rising) of the intended output voltage. The power good pin is pulled low when the regulator is not enabled. It seems like you are looking for a feature that tells you if the input power is good, in which case this regulator is not appropriate.
