Free TI brushless controllers (while they last)

Post by slofunk » Jul 25 2012 9:37am

Hi All,

Sorry if this is a dupe. I wanted to blast it out there to make sure fellow ES folks see it.
I am usually just a lurker but wanted to share!

This link worked for me.

Thanks!

Nice, it will be interesting to see how these compare to the usual ecrazy controllers, thanks. :)

I'm thinking people are assuming this is a TI version of a plug and play e-bike controller.

To me, it looks like an evaluation board for those interested in designing a BLDC controller based on TI parts, and it does not include any output MOSFET's to actually drive a motor. I only took a brief glance, and its not that clear, but this probably is going to be useless for most people.

Thanks for the heads up or I would have totally missed this one! One now on it's way. :D

I ordered one too. I don't mind adding some power FETs and breadboarding it up, but am not going to be able to figure out all the dirty details about additional components. Are there any schematics showing how to build a controller using this chipset?

I too asked for one of these kits. It will be a learning experience for me, big time.

AFAICT this is definitely not a complete "ready-to-use" controller, but rather a parts kit intended for fairly powerful (48v-96V) ebikes and e-motorcycles and similar applications, based on a programmable MCU LM3S8971 "stellaris", one of the ARM series, which is capable of running an RTOS (although I don't know if this application uses one).

Given that some of their MCU eval kits that are already built-up have cost from $100-$300, then for free I suspect it does not include anything except the chips themselves, and the entire PCB design/etc is left up to the experimenter/engineer. For example, one BLDC RDK for this same MCU is $219 here:
http://www.ti.com/tool/rdk-bldc
though it also includes a motor and whatnot for testing.
Software may also be needed as well, although they likely have basic building blocks available included in the SDKs and programming tools and whatnot.

This is a block diagram of what's there (red) and what's recommended (gray):

motor_tn.gif (22.92 KiB) Viewed 1505 times
Unlike most TI stuff this one doesn't have a lot of direct explanation about what it is and isn't, and what it does and doesn't have, with only links to individual parts, and that is another thing that leads me to believe it is just the bare chips, plus on it's kit order page, it is sligthly more clearly listed as just the devices (chips), if I understand it correctly.

Have to wait and see till people get them to know for sure, but they should be useful to those trying to create new controller designs. Hopefully these will do what the "infineon" and clone chips did for Chinese ebike controllers, and make some newer better more versatile ebike/emoto controllers easy to design as fairly inexpensive user-programmable/customizable units, without as much time into the software as Lebowski and others have had to put into theirs. (though they probably won't have quite the feature list ;))

According to TI's site, ship dates for this will start around the end of November 2012, for those still interested in it.

I tottaly forgot about this, but my free samples arrived almost two months ago. I was really happy when I saw size of the box, but disappointed it only had four chips, no any board whatsoever. So, not much use for me, unfortunately.

Free stuff sweet. I would like to experiment with TI stuff too.

AHA! A week or so ago, I spent perhaps two hours lookking for this thread, using google search and other internet searches, and the ES forum search engine, and poring thru my subscribed threads, and couldnt' locate it. :(

TI sent me another notification that the status changed, but the website doesnt' really show anything different, just that it is "Processing".

Same with mine, haven't opened it yet either.

I got a box with 3 moisture sealed static free bags.

The labels say I got 3 each of IC motor driver pwm p/n DRV831200WR and IC isolation amp p/n AMC1200SDUBR, along with one LM5101BMA/NOPB a 2A high voltage high-side and low.

I have no idea what they are, so if anyone can make good use of them pm me a name and address.
