Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. My unit has two boards, a low-power 5V control board and the high power board being discussed here.

And just for the record, I am all about hands-on other than the seemingly endless hours I spend reading datasheets and white papers trying to ucc33722 this stuff. By continuing to use this site, you are consenting to our use of cookies.

I calculated that I need 2A to get a 50nS rise time. I’ll do some research on harmonics and RF and see what I should be looking at. I’m just trying to make sure I understand what’s what and I’ve found that me not asking often equals me misunderstanding.

Playstation 1 motherboard housing fell off, help! I think I could slow it down – at least on the rise – without any real impact on the functionality of my output. Forums New posts Search forums. I think I will be okay uucc37322 heat dissipation as the heatsink is large, but thank you for the information. The answer to 3 is in wisdom that I do not yet possess.

TI Debuts UCC37321/UCC37322 MOSFET Drivers

Another one I found when using mosfet drivers was that the waveform from the output of the fet was so square I was getting loads of harmonics and rf interference. Excuse my terminology, I’m hands on not so much textbook. Couple of things to watch out for. I’m using an Allegro AC current sensor to monitor current and limit it via duty cycle to 30A for now. MB dr pepper said: Mosfet drain current spike and input current spike in full bridge inverter.

OpAmp circuit for temp sensing using diodes Started by Elerion Today at 1: So, I shall plug on ahead and see how it goes.

Input voltage could be either 12V or 24V, and the nature of the load to be driven is unknown – could be inductive or resistive. Now time for me to make a new post trying to understand my circuit protection scheme!

Started by sr Today at 5: Started by chemelec Today at 4: I appreciate any help or guidance – I’m sure the answers to 1 and 2 are in the documents I’ve been through, I’m just not seeing them. If so, in my application I think I could actually slow it down some: Started by Silverboy Today at 7: MikahB New Member Apr 26, For a better experience, please enable JavaScript in your browser before proceeding.


I think I came up with a pretty slick way to mount my 5V regulator and MOSFET to the upper board that makes everything very compact and tidy and lets them connect to a common heat sink.

Even though your mosfet is rated at 75a, that is steady state and in lab conditionsin a switching application the mosfet will spend some time in the linear state while it is switching, using the driver reduces this however you need ta take that into account when working out dissipation.

To participate you need to register.

This is probably overkill, but I would like the capability to possibly run these same parts in a 50 or 60A configuration down the ucc73322.

I will proceed with working towards making my first functional prototypes and hopefully that will help me determine if EMI is a problem or not.

How to create dashed plot in Octave? I suspect the answer is in the data sheet, but I’m unable to decipher it at this point and could use some direction.

My concern is the continuous current output of the UCC which is listed as mA.
