Part Number: UCC23514 Miller clamp seems to be ineffective, there is an abnormal waveform issue with the chip.
U200 and U201 are both the same situation
The red waveform represents the driver, the yellow waveform represents the VDS, and the blue waveform…
Part Number: UCC23514 Hi Team,
Why our UCC23514M cannot stable output with resistor load, but need to parallel a capacitor to simulate the Ciss of MOS? Without the capacitor, the driver's output will have oscillation. Is there parasitic inductor internal…
Part Number: UCC23514 Hi,
I am designing a boost converter with SIC schottky diode and SI mosfet for simplicity. I want to know how to rationally choose which transition of mosfet should be higher or lower. the reverse recovery of SIC diode is very…
Part Number: UCC23514 Hello,
We are using UCC23514 as a SiC Mosfet driver. Because the relative long cable from control board to gate drive board, it is coupled with some high frequency switching noise in MHz range.
Since our swithcing frequency is…

Hi all,
I'm using the following scheme to provide noise immunity to the drive signal path. The drive signal is quite critical and false triggering must be kept to a minimum.
…
Part Number: UCC23514 Hi Team,
When customer evaluated our UCC23514, there is a voltage peak on VDS(opposite MOSFET acting, and Miller Clamp MOSFET turn on normally). He also evaluated NSI6801M, which has larger Clamp Current than 23514, and the second…
Part Number: UCC23514 Hi,
I have any questions.
1. Does "the dedicated pins" written in page 2, "8.3.4.3 Short-Circuit Clamping" of the data sheet mean Vout pins?
2. Is the clamp circuit described in "Figure 9-2 Typical Application Circuit for UCC23514M…
Part Number: UCC23514 Dear TI Team Our customer is considering a circuit that uses UCC23514 to reverse bias the gate of the FET. At that time, UCC23514 has a series of E, M, S, V. Which series is suitable for the above usage? (I heard that the data sheet…
