Part Number: UCC21540A Other Parts Discussed in Thread: UCC21540
Hi,
I am using the UCC21540A gate driver in a multiphase buck configuration. I would like to know if the pspice model from TI.com has any issues with the shoot through protection and the…
Part Number: UCC21540A Hi team,
Could you tell me how much voltage we can use along with functional isolation or between VSSA and VSS?
Is there parameter for it in datasheet?
Regards, Ochi
Kartavya Agarwal said: As previously recommended, the LMG1205 Gate Driver IC is out of stock almost everywhere. As a result, I found an alternate option on TI's website: UCC21540A, which is in stock at TI. Would you have any other recommendations that…
Part Number: UCC21541 Other Parts Discussed in Thread: UCC21222 , UCC20520 , UCC21520 , UCC21540 , UCC21540A Hello,
So basically, I'm trying to find an alternative to UCC21541 with the same pinout. I've noticed the UCC21222 seems pretty identical besides…
I have one idea and I believe it will make a difference.
Change the driver voltage from 12V to 10V with UCC21520, or 8V with UCC21540A, you will see ringing reduction. For MOSFET, you have barely little benefit to drive over 10V, instead you will see much…
Olatuyo,
You can use zener in the driver OUT path with virtually any driver to drop the voltage.
If you MUST have a low-voltage SUPPLY to the driver your options are more limited.
P/n is part numebr.
If this is low-voltage, why do you need any isolated…
Hi Han,
Thank you for your question. I work on the applications team in the high power drivers group.
I see you were looking at our 5V UVLO isolated dual channel gate drivers UCC21520A, and UCC21540A. UCC21540A can safely operate with up to 18V on VDD…
Part Number: UCC21520
Hi,
I have seen a 10kOhm resistor between Gate and Source (see R14 and R12 in the attached fig from tidue55b.pdf), but I cant figure out why the resistor is there. My guess is because measuring purposes without a MOSFET being there…
