Part Number: UCC21540 Tool/software: Hello,
is there a specific reason why the common mode transient immunity of the UCC21540(A) is provided for a VCM of 1000 V, whereas, at any other isolated gate-driver IC from Texas Instruments I looked at the VCM…
Hi Nico,
Nico Hugo said: Would you recommend measuring the Vgs rise/fall times to establish the minimum ON and OFF pulses in our specific application?
Yes, that is the best approach to see how long it takes to fully charge/discharge.

Part Number: UCC21540 Other Parts Discussed in Thread: ALLIGATOR Tool/software: A half-bridge circuit has been designed to drive an inductive load, with a sinusoidal pulse-width modulation (SPWM) signal controlling the switching. However, during operation…
Part Number: UCC21540 Tool/software: Hi Experts,
Customer wants to replace this diode-based rectification to synchronous rectification:
The input is 264VAC peak having frequency 30Khz +-12kHz. The input is square waveform.
Do you think the UCC21540 can…
Part Number: UCC21540 Other Parts Discussed in Thread: UCC21550 Tool/software: Hi,
The UCC21540 datasheet requirement for DT capacitor changed in the November 2024 release where the requirement was updated from >=2.2nF to <= 1nF, please see below.…

Hello experts,
I am Erick, sales in Taiwan, I would like to kindly request for your help with analyze or give me any feedback if there could be any risk to put UCC21540 in immersion cooling.
The immersion cooling…
Part Number: UCC21540 Hello,
I am using the UCC21540DW driver for boost converter to drive top side cooling SIC fets.
The fets have 2 ohm gate resistor inside them.
Can i remove the external gate resistors (to make the layout more effective and small)…
Part Number: UCC21540 Other Parts Discussed in Thread: UCC21222 Hello,
is it ok to place wires in the layout in the bottom layer in the middle of the IC pads and to minimize a little bit the creepage distance of the isolation pads?
Thank you
Part Number: UCC21540 Hello,
I am using the UCC21540DW gate driver for boost converter.
My question is if it is ok to connect the outputs of the fet drivers (OUTA,OUTB) directly to the fets and not to place a series resistors?
The IC will not damage by…
