Part Number: UCC21750 Hello,
During the design for high-voltage applications, I studied a bit about TI gate driver products and their application range. I realized that for the safety of the product in power supply design, it is necessary to choose among…
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…
No problem AM,
Yes, you can use it in any spice simulator. Here is the raw netlist for that purpose: 1524.UCC21750.lib
PSPICE has a "Power NMOS" which is a spice level 3 model:
.model power_Mbreakn NMOS W=1 L=1u LEVEL=3 CBD=1E-9 RDS=1E+06 TT…
Part Number: UCC21750 In UCC21750 driver IC, AT AIN pin with 100nF capacitor is placed, when i am giving power supply to driver, then i am seeing 1.5V V across AIN pin without connecting any resistor or NTC.
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.
our used schematic is attached and the problem we are facing…
We can set up a meeting if you want. You can send me a webex or teams link.
If the Bus is not connected, where is this voltage coming from? Do you have a problem with your bootstrap supply? It would help me if you share your schematic.
Part Number: UCC21750 Hi
How many MOSFETs can be run in parallel on the ucc21750? I don't have a problem with up to 2 at the moment, but I want to know how many will be possible.
It is a 50KW system and will consist of PFC and LLC.
Thanks

Hello,
I am using UC21750 gate driver for a vienna rectifier application. I tied DESAT pin to COM, but still FLT pin is low.
Note: There are 6 gate driver on the board, two of them work as expected. Therefore;
1- I replaced the…
Part Number: UCC21750-Q1 Hello, I would like to ask, is it necessary to add D1 and D2 protection diodes to the external detection circuit of the DESAT pin of the UCC21750-Q1 chip? If necessary, can D1 be replaced with a voltage regulator tube? "Adjust…
