Hello, I am trying to apply IKCM30F60GA for motor driver. I noticed that it has a 380ns deadtime DT_ic on gate drive circuit from the datasheet. Its datasheet also says, deadtime between low side and high side DT_pwm is 2 us.
I would like to know what is the difference between DT_ic and DT_pwm? Does DT_pwm means the pulse width difference caused by DT_ic at U output when the gate drive input has no deadtime? Maybe DT_pwm is a recommended value of the gate drive input?
Solved! Go to Solution.

Hi,
Yes, you are absolutely correct DTic = 380ns is minimum deadtime insertion provided by driver IC to reduce cross conduction of the power switches in case deadtime between input signal Hin and Lin is lower than 380ns. DTpwm = 2us is the recommended dead time between Hin and Lin for the user.
Do revert for further clarification.
