Hello,
We are using the TI ISO5451 in an existing gate Driver circuit.
For driving SiC-semiconductors, we would like to add the recommended external current buffer circuit of the datasheet (pic below) to get more peak output current ability.
Is it still possible to use the active miller clamp function of the TI ISO5451 by connecting Pin7 to the gate of the SiC-semiconductor directly?
The clamping becomes active when the gate voltage is below 2V. Could this result in a problem, if the internal clamping device is active without knowing the actual gate voltage at the SiC-semiconductor?
Thank you for your help.
