Part Number: UCC21520 Hi Team,
We see that there is one 600V diode and resistor(D1/R15) in serial as below picture shown for UCC21520 EVM circuit, may I know what's the purpose for them? Do we need to add them for customer's circuit design?
Thanks…

Hi team,
For our datasheet spec, the OUTPUT signal voltage the max value is 'VVDDA+0.3', the VDDA is the real supply value at PIN16, if this understanding is right?
Thanks…

Part Number: UCC21520 Hi,
A customer has an inquiry about latch-up. ・Is there a possibility that the driver will be latched up? If the driver IC has a COMS structure, I think there is a possibility that a surge may enter the IC due to the FET mirror…
Part Number: UCC21520 Tool/software: Hi,
I want to ask question regarding using relay (G5Q-1A4-DC12) at the switch node of half bridge circuit to connect and disconnect individual transformers contacted in parallel to the circuit. See the attached…
Part Number: UCC21520 Dear TIer,
I have question about single / two channel ios-gate driver.
Why single channel iso-gate driver no use bootstrap circuit in main popular half bridge design?
It looks like a PWM IC with two auxiliary lines is used…

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 As per the Datasheet, if the DT pin is left open: The default dead time is from 0 to 15ns Maximum.
Can you confirm that by keeping the DT pin Floating, will set the dead time between OUT A & OUT B to maximum 15 ns.
In my…
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…
