Hello All,

The following is based on what I've obtained from this PDF:www.ti.com/.../slaa503.pdf

Title: Sensored 3-Phase BLDC Motor Control Using MSP430

Project collateral and source code discussed in this application report can be downloaded from the following URL: http://www.ti.com/lit/zip/slaa503.

Where is the hardware schematic corresponding to the above software?

Hi user4708725,

The closest schematic is the block diagram (Figure 2) of the application report.

The driver block used was a 6x PWM gate driver.

There are several devices that can be used for the driver. Examples of 6x PWM devices include the DRV8301, DRV8302, DRV8303, DRV8304, DRV8305, DRV8320, and DRV8350.

A complete list of devices can be found here:

With some code modifications, the DRV8312, DRV8332, and DRV8313 could also be used.

Is there any supporting hardware that can be used directly without modifying the program?

If I use DRV8303EVM, How to modify the Closed Loop Control?

Hello,

The DRV8303 accepts 6x input so you should be able to use it directly. The changes for the code will need to be for the housekeeping stuff like fault, enable, etc.
