DRV8301 eval kit connectable to MSP430?

Other Parts Discussed in Thread: DRV8301, BOOSTXL-DRV8301, DRV8332, DRV8312, DRV8313

Hi! I'm trying to find out of TI makes some kind of eval kit for the DRV8301 that I can hook to the PWMs/GPIO on an MSP430.  I see the BoosterPack but it's made specifically to jack into a LaunchPad board.

We're driving a three-phase brushless DC motor and need over-current sense to meet UL requirements (ugh).  If there are other options than the DRV8301, I'd love to hear bout them - the design we inherited seems iffy in places, although functional.

All info appreciated!

    Hi Ed,

    The BOOSTXL-DRV8301 can be wired up to any microcontroller with jumpers. The only issue can be with inductance in the ADC lines. What kind of MCU breakout board do you have? 

    What kind of voltage and power requirements do you have?

    Good morning!  We have a proto board coming in with the MSP430 FET: http://www.ti.com/tool/msp-fet430u100usb?keyMatch=msp430f5638%20developers%20board&tisearch=Search-EN#buy

    ..We're just looking to bash a few parts together to get some dev work going while our hardware guy does the board design, we have a small DC motor (5V?, 12V?) that we're going to use to test the software with. 

    We're still in the VERY early stages of this project, we inherited a partial hardware design that uses the DRV to control a fence-gate motor to open and close, not real complex stuff.  The MSP430 handles most of the "business logic" and UI as well as the motor control.

    I'm the software guy so if you need more hardware details, I'll have to pester the man with the soldering iron.  I just ned the quickest way to get the MSP430 talking to the DRV so I can code up a driver and get some low-level testing going.

    Thanks a ton for yoiur response!

    Hi Ed,

    I would probably just take the BoosterPack and jumper wire in from your MSP breakout board. This should be fairly straightforward. You can then check out basic control such as SPI and PWM.

    The BoosterPack is a full drive stage based on the DRV8301 and NexFETs. It just needs an MCU to drive it and power.

    If you motor requires less than ~3-5A you may want to look into an integrated driver such as the DRV8312, DRV8332, or DRV8313.

    Thanks!  I'm going to requisition that booster pack, and pass on the info on the other chips to the hardware guy.

    Much appreciated!
