Part Number: UCC21750-Q1 Here is the pinout of the IC (UCC21750-Q1):
Is it recommended to keep the 'APWM' pin16 floating if unused or advisable to connect to GND (pin9) ?
AIN pin is tied to COM.
Is there any issue in providing a strong pull…
Part Number: UCC21750-Q1 Other Parts Discussed in Thread: UCC21750 Hello,
Our customer have a question about how long will the 400mA current will last to keep the soft turn off function, is that the time when gate voltage equals to the VEE+2v (Miller clamp…
Part Number: UCC21750-Q1 Other Parts Discussed in Thread: UCC21750 Hi Anyone can help us out to know the reason for incomplete switching off behavior of external NPN-PNP booster with UCC21750.

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 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 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 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?
