thanks for info, could you please tell us from where did you get the TB6560 ?

[lucas]

I bought some from this guy:

They aren't listed for the moment but you could ask if he can still deliver.

Hi,

where can get he PCB to build the board ?

I have 2 TB6560 here.

Is a test video or picture available ?

Best regards
Chris

Here's a picture of my DIY version, it's a double sided PCB.

I couldn't find an easy way to design the PCB with decent size power tracks so I had to choose between a nice design with connectors etc. or something that should work, I did choose the second option and came up with a very small PCB with connectors for the power input but soldered wires for the motor connections directly on the board.
I also had to slip the PCB between the pins of the chip.

These have been used on 3 machines and they work very well, even at 2,5 Amp output only a small heatsink is needed, no active cooling like almost every other chip needs.

There's also a German guy who made a design, here's the link:

Hi Luc,

i know the german guy and i have contact via e-mail.

The german version is not finished yet. He have some problems.

Your design is very simple, that´s what i need.

Is ist possible to get 3 PCB´s of your version ?

Do you habe a part-list ?

Thanks a lot.

Bye

The TBQ6560 is a nice little chip, I've been pleased with how it performs. Yes it suffers from being less flexible on setting currents. One point I would make, it's very important to use a low esr capacitor on VM, and a decoupling capacitor very close to the chip for VM supply pins.

[lucas]

Phil,

do you have pictures of your design using this chip?

PCB layout for this one isn't really easy.

I have used SMD (low inductive) current sense resistors on my latest build and the motors are dead silent. They are 0.5 ohms each and the pcb has 3 locations for each coil, so installing one resistor gives a 1 Amp drive, 3 makes a 3 amp drive.

Regards,
Luc.

[pminmo]

Here is one version. Sense resistors are on the bottom of the pcb. SMD 2515 2W.

I like the plugin type of the Naos. Looks like a G250/G540 style of setup.

At what voltages and currents have you tested these chips?

Did you also "intentionally" forgot the power-up and down sequence mentioned in the datasheet?

Nice work.

Regards,
Luc.

PS: I still should have a bunch of soldercup DB25's left over from my mini and mainframe computer service time ages ago, these can be mounted easily with the PCB between the pins.
So you gave me a new idea for an easy configuration...

I went to your site, Phil, and didn't find a reference to this board. You don't have it listed yet?

[pminmo]

Yes I did intentionally skip the "recommended" sequencing, kind of, Enable and reset are sequenced. Since there is no timing spec on the Vdd to VMA sequence, I decided to build it and see if there are any issues. So far no problems.

[jalessi]

Phil,

Do you sell any of these as kits?

How is the performance?

Any Video?

Jeff...

[samroesch]

hmm, not sure how to delete this, sorry.

[pminmo]

Kits, possibly in the future. Performance of the part is very good considering a monolythic IC. No video.

[ggg]

I will try with this IC.
- Anyboby have the Eagle library of this chip to share?
- I'm not electronic specialist, could any any one tell me how to calculate Rsense watts?
_ Phil, I have good references of your schematics, do you have one to share with us?

[jalessi]

Phil,

Do you have PCB's for sale for this?

Jeff...

[pminmo]

Phil,

Do you have PCB's for sale for this?

Jeff...

Sorry, not yet. I probably shouldn't have posted the picture.... I have several designs done and running, but won't have boards built in quantity till I get the last two designs "rung out". And I do this in my spare time when I'm in the mood......
