Part Number: UCC21750-Q1 Hello TI,
The DESAT function requires the 3 external components, R, C_BLK, D_HV.
Could you please share knowledge on the design requirement for the series resistor (R - shown in the figure below) ? What is the recommended value…
Part Number: UCC21750-Q1 Other Parts Discussed in Thread: UCC21750 Hi Expert,
Two questions would like to check with you.
May I know the maximum supply current for VCC pin that customer should consider? I can only find the VCC quiescent current (4mA max…
Part Number: UCC21750-Q1 Hello,TI expert:
I encountered a problem when using UCC21750-Q1. The FLT-Pin was pulled low unexpectedly, but Desat did not have any voltage exceeding 9V.
I don't understand why, this is inconsistent with the description in U…
Part Number: UCC21750-Q1 Other Parts Discussed in Thread: UCC21750 We are using UCC21750-Q1 ( https://www.ti.com/lit/zip/slum718 ) as a Gate Driver in our application and are running the simulations in Ansys for checking the EMI/EMC.
However, upon importing…
Part Number: UCC21750-Q1 Hi team,
Do we have life time testing data of UCC21750-Q1? You can email to me if it is internally only. We have NDA with my customer. Are we showing TDDB curve on this feature?
