Part Number: UCC21520-Q1 Hi team,
Customer plans to use the following negative bias circuit from the datasheet. VDD-VSS=23V, VZ=5.1V.
During testing, customer found that establishing the 5.1V negative voltage takes a certain amount of time, which…
Part Number: UCC21520-Q1 Other Parts Discussed in Thread: UCC21520 Tool/software: Dear Team,
I am using SiC MOSFET where it requires +20V and -5V respectively. The gate driver used is UCC21520. Could you verify the schematics especially where the ground…
Part Number: UCC21520-Q1 Other Parts Discussed in Thread: CSD19536KTT Tool/software: Dear Ti,
We are considering connecting the input MOSFETs in parallel on the PSFB input side to increase the current capacity, and we will be using the UCC21520-Q1…
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:…
Hi Fabio,
Fabio Posser said: According to the datasheet, the input should not be switched from ON to OFF during the turning ON process
This statement in the datasheet is referring to narrow pulses being outputted by the driver. When a narrow pulse…

Hi,
We are using the UCC21520-Q1 Isolated Gate driver for the UCC28951 PSFB. Shall we use single isolated DC to DC at the Primary side for both Gates power…
Part Number: UCC21520-Q1 Hello,
Good day.
Our customer said this transient model is damaged, they downloaded the file and found it can't be used.
Could you please help check if this file is ok, and could you give a instruction for using the model…
Part Number: UCC21520-Q1 Other Parts Discussed in Thread: UCC21520 Hello team,
This is general question.
I believe the difference between ucc21520-q1 and ucc21520a-q1 is UVLO threshold. (5V vs 8V)
What system is beneficial for non-A and what system…
