Hi Team,

What is the internal resistance at #PROCHOT pin?

Best regards,

Hi Hardy,

This is not a specified parameter. What is the purpose for this parameter?

Regards,

Eric

Intel Prochot topology needs 200ohm > Ri + Ragent > 75ohm

Should we ignore the independence of #PROCHOT?

According to the datasheet, the Ri should be less than 60ohm.

Hello, Tiger

In this case, I connect #PROCHOT pin directly to the CPU only through one resistor. No other connection whatsoever.

should I use 60ohn or 0ohm?

I'm confused because our #PROCHOT is pulled up by 50ohm, I couldn`t know the impendance of it.

Hi, Tsai,

You can use 0-ohm.
