Question about confusing Datasheet: TB6552FL
I've trying to find some motor controllers for my UAV blimp and I ran across the TB6552FL by Toshiba(Datasheet @: http://www.semicon.toshiba.co.jp/docs/datasheet/en/LinearIC/TB6552F...)
I'm working on a Eagle library for this component so I can design my schematic around it but I've ran into a confusing area in the datasheet. On page 2 is clearly lists the pins in the following order: 1-GND, 2-AIN1, 3-AIN2, 4-APWM, 5ASTBY, 6VM, 7AO1, 8AO2, etc
My only problem with this is that on page 10 is shows the chip with pin 8 on the "bottom" of the chip but when I refer back to the guide on page 2 that pin should be 9 and the pin labeled 9 should be pin 6. What should I do?
I hope I've been clear enough.. if I havn't I'll post a video.

that drawning in page 2 is a "block diagram" not a pin out pay no attention to where they have the "pins" on a block diagram it is just to show you the fuctionality not to show you the physical location of the pin.

An easier part to interface is the Fairchild FAN8200 - it's 14-pin DIP rather than surface mount, runs 3.3V logic, is rated at 1A per channel, and only requires 2 control signals per channel. That's what I use on YARB 1.0. The Fairchild part has been discontinued, but you can still find some here -

The Sanyo LB1836M is the designated replacement. See -

Thanks for that information, time to redo my schematic!

Sorry for the double post. What CAD Software did you use for your board? I'm using Eagle and it doesn't have the Sayno or the Fairchild and that's really annoying :(

I use Eagle. For the FAN8200, just look in the library for a 14-pin DIP.
My schematics and layouts are here -

Look at bfin-radiomotor-v2 or bfin-motor-v2 to see how the part is used. The FAN8200 is a very nice chip, so I was really sorry to hear that it was discontinued, but there are distributors who stockpiled some quantity, and the Sanyo looks to be equivalent.
