Hello Masazumi,
Thank you for the interest in the LM5101C. I support this device and will work to answer your questions.
From the attached file I see you are asking what is the minimum value for the LO and HO turn on and turn off propagation delay.
We will not be able to provide a guaranteed minimum specification, as this parameter minimum value was not determined before the device release.
I have a question regarding why this value is a concern. In most applications the maximum propagation delays and the delay matching, tMON and tMOFF, are the concerns for driver timing in the application. Why are you concerned if the propagation delay is less than the typical, if the delay matching is guaranteed in the datasheet?
I will research data that I can provide propagation delay lower values that can be expected in the device. These would not be guaranteed parameters however.
Regards,
Richard Herring
Hello,
Thank you for your reply.
The reason is necessary to adjust the dead time in detail to raise the efficiency and prevent through current.
Thank you.
