Part Number: UCC21521
Tool/software:
Dear TI,
I have built a prototype PCB where I wanted to have SiC MOSFET in half-bridge architecture. I used TI dual gate driver with SiC but I got into an issue with high ineffective switching. I would say it…

Part Number: UCC21521 Tool/software: Hi team,
I have a customer with the below question on the UCC21521. Let me know what you think and thanks in advance!
"I had a question about a UCC21521 Isolated Gate driver. In the datasheet, on the first page…
Part Number: UCC21521 Other Parts Discussed in Thread: UCC21550 Tool/software: Dear TI Team,
I would like to get the UCC21521 TINA Model, which has been mentioned in many forum. But now in site i am not able to get it!
Similarly in LTspice we are…
Part Number: UCC21521 Tool/software: Dear TI design support,
I experience the slow intermittent switching in half-bridge and dual gate driver UCC21521, I used negative stage bias with Zener diods for my SiC MOSFETs and wonder why the gate signals…
Part Number: UCC21521 Other Parts Discussed in Thread: UCC21551 Tool/software: Hello ,
I have downloaded a PSPICE transient model of UCC21521 from the TI website and ran a transient simulation. However, the simulation fails to converge.
In transient…

I'm using one gate driver signal to drive two FETs in parallel to manage current requirement of Motor in H-bridge Configuration (<75A).
But, UCC21521…
Part Number: UCC21521 Hi,
I am trying to simulate PSpice model of UCC21521 with MOSFET ( NVHL027N65S3F ) Hex bridge and flyback diodes(IDW80C65D1) parallel with it . We want to estimate the current through the flyback diode. The motor's coil resistance…
Part Number: UCC21521 Hi!
We are trying to simulate and debug a circuit where UCC21521 is used to drive Hex bridge MOSFET( IXFH56N30X3 ) for motor load. In the simulation, we used IXT_96N15P MOSFET. We are facing convergence issues and the upper MOSFET…
Part Number: UCC21521 Hi!
We are trying to simulate a motor driver circuit in TINA TI software. The circuit has UCC21521 motor driver, connected to a hex bridge MOSFET (IXT_96N15P,NMOS) configuration to drive a three phase BLDC motor. We generated PWM…
