LMG5200: The requirements on LMG5200's HI and LI inputs

Hi BU team

Would you help share what are the requirements on LMG5200's HI and LI inputs?

If HI is always high and LI is always low, SW can keeps output high. Is it right? Don't find the timing requirements on HI and LI inputs in the datasheet.

Thanks

Hello,

If HI and LI are fixed with HI high and LI low, the high side device will conduct and SW to PGND will register a high output. Your statement is correct,

Can you clarify which timing requirements you are looking for with these input signals? I want to see which section in particular you are interested in.

Thanks,

Zach

Hi Zack

No timing requirements on HI/LI inputs can be found in the datasheet. Users don't make sure that there isn't this requirements or this requirements are missed.

Thanks

Hello,

Here is an excerpt from the datasheet that includes timing requirements for LMG5200:

Can you help me understand specifically which timing requirements you are looking for that are not included in the datasheet?

Thanks.
