DRV8301 is a pre-amplifier for 3-phase motor controllers. It is programmable through SPI, handle 60V, contains a 1,5A buck converter and support for 2 current sensors. DRV8302, DRV8303 and DRV8305 are other variants of this. I really want to dig into DRV8305, but they are a bit hard to get and I had my eyes on DRV8301 for quite a while.
I have a dev board from TI with this, and I am a bit concerned about the total footprint with all components, but I want to give it a try. The buck converter will feed MCU and RS-X transceiver, so it will be interesting to see what I can achieve.
