My concern is the continuous current output of the UCC which is listed as mA.
TI Debuts UCC37321/UCC37322 MOSFET Drivers
I’m using an Allegro AC current sensor to monitor current and limit it via duty cycle to 30A for now. Articles Top Articles Search resources. Icc37322 dr pepper said: OpAmp circuit for temp sensing using diodes Started by Elerion Today at 1: How to create dashed plot in Octave?
I’m a mechanical engineer, so this is way outside my wheel house! To participate you need to register.

The answer to 3 is in wisdom that I do not yet possess. I think I will be okay on heat dissipation as the heatsink is large, but thank you for the information. So, I shall plug on ahead and see how it goes. Ufc37322 time for me to make a new post trying to understand my circuit protection scheme! I’ll do some research on harmonics and RF and see what I should be looking at.
My unit has two boards, a low-power 5V control board and the high power board being ucf37322 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 understand this stuff. I calculated that I need 2A to get a 50nS rise time.
UCC37322 – Am I On The Right Track?
Input voltage could be either 12V or 24V, and icc37322 nature of the load to be driven is unknown – could be inductive or resistive.

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. 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.

Even though your mosfet is rated at ucc33722, 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.

Thread starter MikahB Start date Apr 26, I’m just trying to make sure I understand what’s what and I’ve found that me not asking often ucc37232 me misunderstanding.
Another one I found when using mosfet drivers was that the waveform from the output cuc37322 the fet was so square I was getting loads of harmonics and rf interference. Mika, yes your assumption is correct, that is what I meant. Forums New posts Search forums. Both boards are about 2″ x 2. I do not know if that rule-of-thumb was more for turning on fast or for keeping it on.
Started by sr Today at 5: I suspect the answer is in the data sheet, but I’m unable to decipher it at this point and could use some direction.
