Other Parts Discussed in Thread: UCC28180, UCC28070A
Hi,
I am wondering, if the UCC28180 circuit tolerates short negative peaks below -0.3V, measured at gate drive output. We have measured such peaks, even ~-2 V, originated from oscillation on the trailing edge (gate drive shown in green, FET drain shown in yellow, output voltage shown in blue). There was a resistive load on the EVM-573 board, ~350W).
The peaks are short, maybe about 10 ns in FWHM. Some TI gate driver circuits have lower allowed negative values allowed for short peaks, < 200 ns.
Is it the same with UCC28180 ? The measurements were done with a Keysight DSOS104A- oscilloscope and Keysight N2791A 25 MHz differential probes.
