TLE7209 or MC33186 H-Bridge Breakout

Post by russian » Sat Mar 09, 2019 9:39 pm

We need some H-Bridge so why not TLE7209 or MC33186, these seem to be compatible enough and some older versions available from China?

TLE7209-3R has recently replaced TLE7209-2R seems to be pin compatible.

Why would we ever use an NRND part when there are better parts available for less money that are still active? Seems pretty foolish to pick a random part without any research, especially one that’s NRND.

For example the ST L9960 is designed for ETB applications, automotive rated, fully protected, adjustable over current protection, SPI fault detection, etc. Oh, and they’re <$5 in single quantities. And there’s also a variant that’s two chips in the same package to save space if you need to drive two motors.

Top message corrected - there is a TLE7209-3R not NRND recent revision.

PS: I am always open to any other suggestions. As someone begging for any help, KiCad help included, I would love to have any other H-Brigde breakout board, ideally with a two-row side connector.

I dont think that TLE7209 is picked random without any research.

That's actually the driver found in each and every Bosch-ECU for almost 20 years now.

Ah okay. The OP made it sound like it was already decided, and provided no context or reasoning :)

The Infineon and ST parts look quite similar functionality-wise, but the Infineon is kinda hard to source. I'm not a fan of sketchy ebay parts. The older 7209-2 is available from normal places, but it's NRND. The new -3 isn't in stock anywhere (yet?).

The interface on the L9960 and TLE looks similar enough that they may be compatible (save for SPI commands and stuff), so I tacked a few L9960 on an order I was already placing.

@russian : what kind of connector is useful on the edge of the board for you?

For this to be used on the blue nucleo wing it would be great to follow the viewtopic.php?f=4&t=450&p=32039#p32039 and viewtopic.php?f=4&t=1471#p31990 using viewtopic.php?f=4&t=1473#p32038 header

The7209-2R are still in stock at both Mouser and Infineon.

The 7209-3R looks to be just a new revision, and it might be they want to sell out the 2R before releasing.

NXP also have newer versions than the 33186 that are identical.

These seems to have become the "standard".

So by using them, we are sure they works perfect with all E-throttles made the last 15-20 years.

(Standalone ECU's like LINK and MaxxECU use it as well)
