| Jan 3, 2020 at 11:16 | comment | added | user3807616 | @m-walker95 What about mcp8063? It is super small and seems simple to use with just a few pins. It is designed for sensorless BLDC and low power solutions - docs.rs-online.com/8090/0900766b813269aa.pdf | |
| Jan 2, 2020 at 17:50 | comment | added | Ocanath | @user3807616 the DRV10970 only works with sensorized motors. It would not work with the EMAX 66KV motor you suggested. | |
| Jan 2, 2020 at 17:22 | comment | added | m-walker95 | You are correct, Chris . I am more familiar with using N channel devices to drive motors that is why I say that the MCU would not be able to drive the FETs. I still would suggest using N channel FETs and a gate driver though or an integrated solution. | |
| Jan 2, 2020 at 16:56 | comment | added | Chris Stratton | The claim that the FETs cannot be driven without a gate driver is false. Suitable ones can be driven directly from an MCU, and typically are in such applications. It's larger devices or using N channel parts as high side switches where this would be a problem - the link in the question does do that, but it's only one of many reasons why that link is not good guidance for this project. | |
| Jan 2, 2020 at 16:52 | comment | added | user3807616 | thanks! By following your recommendation I found 5v version - digikey.com/product-detail/en/texas-instruments/DRV10970PWPR/…. Why do these chips are so hidden? | |
