LM5100A: LM5100A

Part Number: LM5100A
Other Parts Discussed in Thread: LM5100B,

Hello,

For LM5100A & LM5100B, I couldn't find information regarding RHI and RLO which are shown in the picture below taken from this document: https://www.ti.com/lit/an/slla385a/slla385a.pdf?ts=1643957101671&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FLMG1020

What are the values of these resistances in LM5100A & LM5100B ?

Best regards,

Arin

Hi Arin,

These values can be calculated using the VOH and VOL specs divided by the current they are measured at, as described in the linked E2E thread

Here are the values for the LM5100 devices.

For example, the values of RLO for the LM5100A at 25C can be calculated by VOL/ILO = 0.12V/100mA = 1.2Ω

Thanks,

Daniel W
