Hi Team,
In below spec, can I say the max reverse current that is -11mV/Rds(on)?
Currently, customer has -200mA on 12V and we would like to use ideal diode controller + NFET to block the reverse current, but it looks like that it may still pass through a little of 11mV/Rds(on)?
Regards,
Roy
Hi Shiven,
Thanks for comments. For example, if NFET Rds(on) that we used is 11mohm.
For the threshold for RCB would be -11mV/11m = -1A
As you can see below, there was negative current initially. (-200mA) Does it mean LM74700-Q1 can't block the current?

Hi Shiven,
Not sure the comments. Do you mean that it's the maximum reverse current would be happened?
-11mV/RDS_ON is the max reverse current.
May you help comment more detailed?
Currently, customer has initial negative current around -200mA and -150mA when doing load transient. We would like to check if LM74700 can block it completely or not.
As I know, only VAC < -11mV, the MOS would fully turn off to avoid reverse current. Do you mean that the reverse current would be lower in regulated conduction mode?

Roy
