Parallel the TB6612FNG?

Post by johnyradio » Thu Dec 06, 2018 1:43 am

These sites say the TB6612 can be paralleled. Is that true?

Is it simply a matter of connecting AO1 to BO1, and AO2 to BO2?

Any extra components needed?

thx

Why do you want to parallel it? If you need more current, simpler to use something rated for that higher current.

That's also an option. I'm looking at all factors, including price, size, parts count, and so forth.

From a technical viewpoint, I'd like to know if paralleling the TB6612FNG works without issue.

Grateful for technical info.

Thx!

It will probably work based on my memory of the chip. Googling reveals that few people have done it.

Thx. I need to run at least 2A, at least 100 kHz. This chip can do that, if it can run parallel.

I haven't found anything else with similar specs for a similar price. Suggestions welcomed!

Cheers

Forego that extra cup of cappuccino tomorrow and splurge!

Treat yourself to a slightly higher priced motor driver that can handle 2.6 Amperes (5 A peak) without any hassle at all: https://www.pololu.com/product/2997

That TB9051FTG chip only goes up to 20 kHz. I need 100 khz or higher.

I don't need 2.6A. 2A is enough.

Also, if a paralleled TB6612FNG gives me what I need, buying a more expensive product isn't "splurging", it's wasting money for no benefit.

Who knows? The professional motor driver engineers don't hang around on the hobby forums.

Let us know if it actually works.

Well, of course you do!

I did mention my frequency requirement above.

Not necessarily important, because this thread isn't asking for chip recommendations.

This thread is asking how to parallel the TB6612FNG. If you don't know, that's ok! Maybe someone else does.
