Hi Ethan,
UCC21550 has multiple different UVLO options listed on the datasheet. If I remember correctly, the PSpice model should be the 12V UVLO option, which is fine in your case. Your waveforms shown earlier indicate that the gate driver is in fact…

Tool/software:
Hi, I need an isolated gate driver that drives the gate of this IGBT - STGP10H60DF at 60Hz switching frequency. How big should the bootstrap capacitor of UCC21542DWKR be for this case? I think it is very large (>50uF…
Part Number: UCC21542 Tool/software: Hi,
I am working of a DC2AC converter using your tools and the above reference design material. I need some clarification on the measurement of the inductor current for the inner current control loop. My questions…
Part Number: UCC21542 Hello experts,
I'm working on a board that uses UCC21542 to drive an H-bridge.
Due to board limitations I would get a better gate connection if I connect the OUTB pin to the high side FET and the OUTA pin to the low side FET…
Hi Babatola,
Apologies for the late response! The thread got closed due to the green resolved button.
On a breadboard, there is definitely much more parasitics coming into play here. Some of the most important areas to keep a short as possible loop would…

Hello, TI:
I use UCC21542 to drive a half bridge module, of which the schematics are presented at the end. Each arm of the bridge consists of two MOSFETs in parallel. The auxiliary power supply for each arm is 15V (isolated). A…

Hello Team, I want to design an isolated gate driver. The Switching voltage is between 20 and 48V, and the frequency can be from DC to 20KHz. The IC UCC21542 uses a bootstrap circuit to increase the Gate voltage of the high-side MOSFET…
Part Number: UCC21542 Hello,
I need to drive several MOSFETs on lines ranging from 270-530VDC. As these are used for heaters, due to the application, they're expected to operate at 100% duty cycle for minutes. The connectivity is shown below.
In the…
Part Number: UCC21542 Hi Expert,
May I know if we have drop-in replacements of 2EDS8265H and 1EDB9275F? That's perfect if you can provide competitive tables to show our performance benefits. Thanks a lot!
Regards,
Jared.
