MCF8316A: Adding external power mosfets to integrated gate driver motor control IC

Part Number: MCF8316A
Other Parts Discussed in Thread: MCT8316A,

Hello,

I have an interest in the MCF8316A and the MCT8316A for a potential BLDC motor control application, but this may require higher power than achievable with these ICs. I read in this article (https://e2e.ti.com/blogs_/b/analogwire/posts/code-free-motor-drivers-streamline-bldc-motor-design), at the end of paragraph 2 of "Method No 3" :

"For motor applications that use less than 70 W, such as vacuum robots, residential ceiling fans or pumps used in washing machines, you can choose devices with integrated MOSFETs to further reduce board space. The MCF8316A and MCT8316A devices support up to 8-A peak current for 24-V applications. For high-power applications, you can place power MOSFETs on the board with the gate driver and motor control integrated into one chip."

The last sentence makes it sound like I could add power mosfets with a higher current rating external to either of the two previously mentioned ICs for a higher power application. Is this correct? If so is there any reference documentation on this or an application note?

Thank you,

Ryan
