  RE: UCC5350: Switching frequency

  Hi, Eduardo, Welcome to e2e, and thanks for your interest in our devices. The maximum switching frequency is a function of power dissipated in the driver, which is dependent on the load (mosfet or IGBT gate) being driven. Please see sections 11...

  UCC5350: May I know what is the error in this circuit

  TI Thinks Resolved

  Part Number: UCC5350 Hello, May I know what would be mistake in this circuit. Vp is a 5V pulse Vcc2 is 15V, Vcc1 is 5V. If I give 15V pulse directly to the MOSFET, it is working fine. But if I connect the driver IC, simulation is not converging...

  RE: UCC5350: Simulating the Typical characteristics of this device using LTspice.

  Hi Audrey, I wanted to simulate the test conditions given in datasheet. I was not able to do so. I have used the same circuit as given in datasheet. But now I think I have start using the IC for gate drive rather than testing it Thanks for your...

  RE: UCC5350: Delay time of Miller Clamp

  Hi Kuramochhi, The Miller clamp is activated when the device turns off (input is low) and the gate voltage (CLAMP voltage) referenced to VEE2 goes below VCLAMP-TH (2V). It is released when the device turns on (input is high). The Miller clamp delay...

  UCC5350-Q1: active miller clamp

  TI Thinks Resolved

  Part Number: UCC5350-Q1 Hi team, Could you confirm the active miller clamp trigger conditions? I think it should be IN=L and Vclamp falls below Vclamp_th. Could you also share the hysteresis spec of the internal miller clamp comparator? Like hysteresis...

  RE: UCC5350: How to reduce gate ringing on IGBT gates using ferrite beads

  Hello Tony, The layout of the driver looks close to the IGBT with short traces. It seems the ringing is improved from the previous scope captures so it seems the bead is helping. To possibly reduce the gate voltage disturbance further, the turn on...
