Part Number: UCC21755-Q1
Hi,
I am designing a low voltage high current traction inverter (72V, 150A) switching at 20kHz using UCC21755-Q1 driver ICs. I am planning to use bootstrap circuitry for all the top switches and split the bootstrap voltage thereafter…
Part Number: UCC21755-Q1 Hi team,
About Figure 8-5. DESAT Protection, w hen DHV turns off after internal discharge FET turns on by turning IN = "low" from "high", I am worried about DESAT-COM voltage rising (or ringing) amd that leads malfunction OCP event…

Hello everyone,
I'm working on a half-bridge circuit with a booster using UCC21755-Q1. However, I'm having issues with the usage of VEE (Negative supply rail) and…
Part Number: UCC21755-Q1 Other Parts Discussed in Thread: UCC21710 Hi,
We are using a UCC21755-Q1 gate drive to run two SiC MOSFET in parallel, the Rgon=15ohm for each one of them, and no capacitor has been used in the gate drive path. As soon as we apply…
Part Number: UCC21755-Q1 Other Parts Discussed in Thread: UCC21750 , UCC21732-Q1 Hi, I am looking for to have a PCB made that isolates 4 x 850V DC voltages so that the connection is not permanently live. This 4 voltages are only used for sensing so they…
Part Number: UCC21755-Q1 We plan on using the UCC21755-Q1 to drive multiple mosfets in parallel. The power supplies are +15V/-5V
Is it okay to connect OUTH and OUTL pins directly together at the IC and run a single PCB track to the gate of the mosfets…
Part Number: UCC21710-Q1 Other Parts Discussed in Thread: UCC21710 Hi
This is Reza. I am a Ph.D student at University of Maryland at College Park. I do have following design questions about the TI's impressive gate drivers UCC21710, UCC21717 and UCC21755…
