New products: G2 High-Power Motor Driver 18v25 and 24v21 (and price drops for other G2 drivers)
- 15 August 2017Hi, 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.

Video: Setting the Current Limit on Pololu Stepper Motor Driver Carriers
- 31 July 2017Hi, 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?

- 31 July 2017Hi.
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.

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

New product: 12V, 2.2A Step-Down Voltage Regulator D24V22F12
- 3 July 2017Hi, 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.

This is one of the ones where we do not disclose the schematic.

- 1 February 2017Hi, David.
Details for how the enable pin functions and its threshold can be found in the "Connections" section of the D24V50F5 regulator's product page.

New D24V150Fx 15A step-down voltage regulator family — our highest-power regulators yet!
- 16 November 2016Hello.
We do not have the available output current vs. ambient temperature characterized (the available current depends on several factors). In general, the regulator is limited by heat dissipation, and the higher your ambient temperature, the less current will be available. The maximum continuous current graph on the product page is for the hottest part of the board getting to 125°C; the thermal shutdown is around 160°C, inside the regulator IC.

- 4 November 2016Hi.
We do not have that characterized, and I do not have a setup to test it well, but I put a 6 V unit on my scope with 24 V in, and I'm seeing around 35 mV peak to peak across a wide range of loads.
