It's about time.

Wonder what the pricing will be?

Sounds like a maxim chip I heard about on the EV tech list that's also 'not quite' available yet.

I think the recent EV tech push because of high oil prices is pushing chip makers to make new intergrated soltions like this - great!! We'll have to be patient a bit though, maybe in a year or so these will be easy to get for "normal" people.

Awesome!

They must be following the desires of Electric Vehicles and doing what they can to give us what we want.

Excellent!

Can you imagine that... one chip and you could know all the voltages of 12 cells. That's just fantastic.

Did any one fill out the form to "qualify" ?

This is probably a test market-without-manufacturing-it-yet form. Power of the internet is placing these things in the marketplace faster, i hope.

I want one, with better interface.

Wow that's a great find!

Who here can or have the skill to build the ext circuit that could show voltage to a LCV display like the one of the C-A? 2 x 16 ch or 4 x 16ch LCD..

I'm not very good to program pic chips.. i'm better with analog.. but if someone here could realize that circuit i'm sure MANY of us would be interested to get the schematic!!!

I have used LCD displays with PICs before and could most likely do this, but the problem is that this type of chip has not yet been released, and we don't know how long yet 'till they are.

LCDs based on the standard hitachi type chips are fairly easy to work with, but some offerings have timing issues that need to be tweeked in software to work correctly. I often use RS-232 comms instead of LCD modules when prototyping, since this is much easier to use (with hyperterminal), has no limit on number or size of displayed text, and it is even quite easy to write a small visual basic program to have a much more complex display and control interface if one needs this. I used RS-232 for my BLDC controller prototype, and this made it easy to display data on screen while also being able to adjust variables used to control motor parameters. Of course LCDs are great for their size and make your project independant of computers when the design has been well tested. And of course we can have both too!

BTW, what would you like to do with this kind of setup anyways, Doc?
