Part Number: UCC21750QDWEVM-054 Tool/software: Hi,
I am using the UCC21750QDWEVM-054. Looks like the peak output current depends on the load capacitor, and it will increase the current by increasing the output capacitance. For instance, the output current…
Part Number: UCC21750QDWEVM-054 Other Parts Discussed in Thread: UCC21750 With the help of thi sdesign referance I am developing mine gate driver with UCC21750 IC. For signal integretity i am going with differentinal gate PWM signals. In design I found…
Part Number: UCC21750QDWEVM-054 Dear team,
If SiC is removed, What is proper operation of GATE_HS and DESAT pin status?
- IN- : GND
- IN+ : 10KHz PWM
Above input condition, Output is always High with FLT signal. Is it normal operation? Please…

Hello Experts, I have the following components:
Wolfspeed Motherboard (MOD-MB-HB-0900V-40A) Wolfspeed Power Card (MOD-PWR-MM-C3M0016120K) Texas Instruments…
Hi Damith,
Thats right, IN+ and IN- are expected to have VCC/GND wrt to GND, not a differential signal between them.
It is best to use differential to single ended option. We have such implementation as a reference design in the following EVM, you…
Hello Emmanuel,
Full gaer board schematics and design files can be downloaded here. https://www.ti.com/lit/zip/sluc703
Please note that the critical signaly for this issue are most likely the SPI, not the PWM. Please review the SPI signals and share…
