ADM1177 TIMER pin behavior

Hi

I would like to ask about ADM1177 hotswap device.

Can I ask in engineerzone?

 

I would like to know about VTIMER behavior in figure 32 and 33.

Datasheet RevC P13 of 24 say

"A hot swap fails if the load current does not drop below the overcurrent fault timing threshold, V OCTRIM , before the TIMER pin has charged up to 1.3 V."

This description says (6) timing in Figure 32 ,I think.

But VTIMER voltage is not changing.

 

I would like to know when/how does it check the VOCTRIM .

 

Thank you for your cooperation

 

moto
