Hi Babji,

Would you mind sharing your motors specifications? The MCF8329EVM can be used in drone applications, but you may be able to use the MCF8316A or MCF8315A to save on PCB space if the motor is suitable for those motor drivers.

Regards,

Joshua

Hi Joshua,

Thanks for the response.

We are using various motors for different applications, all within the specifications of the MCF8329EVM. This is just for testing purposes. We aim to increase the current to up to 60A while keeping the voltage below 60V. Can I use multiple parallel MOSFETs to achieve the desired current ratings, or is there something else I should consider changing?

Also, this EVM doesn't have any BEMF sensing. Is it ok to use for drone applications.

There should not be an issue with using parallel MOSFETs.

I would recommend taking a look at our Driving Parallel MOSFETs application brief for tips on layout and designing for parallel MOSFETs.

The MCF8329A can be used for drone applications. The MCF8329A has internal BEMF sensing which is used in multiple features of the MCF8329A, for example determining when to handoff from open loop to closed loop.
