Part Number: UCC21540 Hi team,
Our customer has some questions of UCC21540.
1. DT pin setting: if they don’t need to use this deadtime setting, can we pull this pin to GND directly?
2. About the CMTI spec: how to test this spec, or how to check whether…

Customer normally decaps and checks the die of the components before a run.
For TI UCC21540DWKR, they found that the die showing a different print ID. Traditionally, TI part# on chip matches that in the die.
Part Number: UCC21540-Q1 Hi team,
Are both of OUTA and OUTB is "L" state @ one of them is under its UVLO_OFF threshold? Or Just one output is "L" state @ its VDD is under UVLO? For example, If VDDA is under VVDDA_OFF, is only OUTA "L…

Part Number: UCC21540 Hi sirs,
UCC21540 has 2 output rails A and B. Are they (A and B) independent operation? Usually, A is put on high side, and B is on low side. May I config them in A at low side, and B at high side with correct PWM change?
Part Number: UCC21540 Dear Teams,
Could I ask whether UCC21540 can drive SiCFET? Customer is looking for isolated gate driver with disable function that can drive SiCFET, do you have any recommendation?
Part Number: UCC21540-Q1 Other Parts Discussed in Thread: UCC28951 , UCC28950 Hi,
in our Phase-Shift-Full-Bridge DC/DC we have the issue, that the primary (HV-Current) has not the expected waveform. We tried several things to get an idea why:
First we change…
