Well, my first suggestion would be to have a heater which would keep the IC above -40º which is what it is rated at. If you want to get a bit more sophisticated you can add a temperature sensor to control the heater.Hi,
First post....
I am looking for a driver similar to IR2110 for a 400V bridge BUT it needs to operated down to -55C. I've searched but could not find anything.
Anyone feel like helping out?
That or offer him a similar device and/or option that can operate down at -55 degrees.What do you expect us to do? Open up a fab that produces Mil Spec equivalents of common parts? We should be able to put that together for a mere 4 billion in venture capital.
You beat me to it!Well, my first suggestion would be to have a heater which would keep the IC above -40º
My suggestion was not as flip as it may have sounded. I was reasonably certain that a part with the specifications required did not exist. Others have pointed out that controlling the environment of the IC's may be an easier task, but when the application is mission critical sometimes that just won't do. I also have a suspicion, given the requirements, that other things besides the driver chip are going to have a problem at -55 degrees C. That's cold enough to where you need to eat ice cream when you come inside to prevent your teeth from cracking when you drink coffee or tea.That or offer him a similar device and/or option that can operate down at -55 degrees.
Always remember that -55 is the ambient operating temperature. Clever is a man who can ensure the operating temp in a harsh environment.
TI and National have similar parts, but they do not match the specifications you need.
No need to answer that way.What do you expect us to do? Open up a fab that produces Mil Spec equivalents of common parts? We should be able to put that together for a mere 4 billion in venture capital.
I answered that way because I'm reasonably certain that it is about the only way to get the chip that the OP requires. You may have thought the answer was smart-alecky but I assure you it was dead serious. In a military application the cost of a custom design assuming you can find a fab might be just a bit less then building a fab from scratch. Still you need deep pockets or a very large volume to amortize the cost.No need to answer that way.
You don't by any chance happen to be working for the Iranian government, huh?Some military designs are mission critical and require -55C operation with no warmup time.
Doesn't matter. I don't think there are any fabs there. At least nobody's mentioned being concerned about all the high tech silicon being produced there. It's also pretty tough to get the PhD in materials science with all the distractions.You don't by any chance happen to be working for the Iranian government, huh?

It's OK, language is very nuanced. I'm sure that your English is way better than my Portugese.Sorry for my misunderstanding.
It was rather a question of expression, not of language. I though you were being sarcastic.It's OK, language is very nuanced. I'm sure that your English is way better than my Portugese.
