Hi Hiroki-san,
Thank you for your investigation.
A similar failure has occurred once before, making this the second time (two ICs). We will first ask a testing agency to investigate the IV characteristics. Best regards, Hiroshi

Hi team,
Could you give me the imformation about the topic in question?
1. I_VCCI quiescent supply current at VCCI =5V - 18V
2. Supply power to INPUT SIDE at VCCI =5V - 18V
When I tested UCC21520DWR, VCCI - GND shorted…
Part Number: UCC21520 Other Parts Discussed in Thread: UCC21550 Tool/software: Hello, can i use UCC21520 to drive HV(600V) MOS? If it cannot work, could you pls promote a suitable device? Thanks a lot!
Part Number: UCC21220 Other Parts Discussed in Thread: UCC21520 Tool/software: Hello,
Can I ask if the parts will be enabled or disabled when their DIS pins are opened ? The descriptions in their datasheets sounded differently for me when compared tables…
Part Number: UCC21520-Q1 Other Parts Discussed in Thread: UCC21550-Q1 Tool/software: Hi,
I’m experiencing issues with a PFC design connected to the grid, where the SiC MOSFETs are getting damaged.
After some investigation, we found that the output…
Part Number: UCC21520 Tool/software: Dear whom it may concern,
Hi, I am designing a half-bridge gatedriver circuit with a bias circuit to drive the 800V mosfet. The basic idea is to generate a biased 20V voltage across the GS pin of the mosfet when the…
Part Number: UCC21520-Q1 Tool/software: Hi, you have an update on the datasheet regarding capacitor on DT pin.
We have 10nF on our design, what's the impact? It's mandatory to change?
Thank you.
Revision of datasheet for the part from 2020…
Part Number: UCC21520 Tool/software: Hi team,
My customer is using our UCC21520 but met some negative ringing at OUTB pin, so they want to add an external diode as below. And the leakage is 20mA.
If this is acceptable action for our part and any side…
