Part Number: UCC21755-Q1 Tool/software: Dear Expert
Use UCC14141 and UCC21755. UCC21755 requires VDD to add at least 10uF to COM. For UCC14141, when the capacitance between VDD-COM is 10uF, VEE-COM needs to add 50uF.
The current question is whether the…

Hello
Please, I am having an issue with my gate drive output where one signal looks higher than the other.
Here is the trace:
The green is high-side gate drive with +10/-10V.
Blue is low-side gate drive with +20/-5V.
My problem…
Part Number: UCC21755-Q1 Nice to meet you. I am writing this because I want to know about the Gate Driver Desaturation Protection Flow.
From what I understand, firstly in the Normal Operating situation, IGBT turns on -> Vce goes low -> DHV turns on …
Part Number: UCC21755-Q1 I have designed a gate driver card wherein I have tied the FLT signal together for HS and LS driver ICs. I aim to drive an inverter using three such driver cards (one driver card with 2 driver ICs, HS and LS drive one H-bridge…
Part Number: UCC21755-Q1 I have designed a gate driver card to support a traction inverter which has a rating of (60V rms output, 60A rms output). I have designed a single driver card to support functioning of one single leg/ Half bridge of a 2-level VSI…

Happy New Year 2024.
I'm a new member and this is my first question/request. Please direct me to the correct channel if the question or request is inappropriate for…
Part Number: UCC21755-Q1 Hi,
For power converter design using UCC21755-Q1 driver IC, if I do not utilize the AIN pin. Then is it advisable to keep the pin not connected to anything?
Part Number: UCC21755-Q1 Hi,
Is it possible to use the UCC21755-Q1 AIN pin to sense output ac voltages or currents, also what are the other use cases of the AIN pin except dc-link voltage sensing and temperature sensing as I see the input voltage is limitied…
