LM73100 R_IMON calculation formula

Maciej Lasota

Other Parts Discussed in Thread: LM73100EVM, LM7310

Hello,

There is formula and example for R_IMON value calculation in the datasheet (SNOSDC0A – OCTOBER 2020 – REVISED DECEMBER 2020):

How it is possible to get 549ohm with that? I guess there is some mismatch with the powers of 10. What is the correct formula?

Thanks!

P.S. It is not possible to select the LM73100 in the "Part number" field when creating new thread. There is only LM73100EVM available.

Hi,

1. Yes you are right. Formula is incorrect. It should be +6

2. Please select LM7310.

Hi Kunal,

1. Thank you for explanation.

2. Why do you recommend LM7310 instead of 73100?

I am a bit confused, because when wanted to check availability of the LM7310 there is information for LM73100PWR provided and "out of stock" status:

Regards,
Maciej

Hi Maciej,

LM7310 is same as LM73100. In system it is named as LM7310.

Hi Kunal,

So why there are 2 part numbers for that IC?
