I'd like to use this device for current limiting on the SD Card power circuit.
Could you please tell me which should I use equation 1 or Figure17,18 in datasheet(SLVSCJ0C) page.15?
I think that both results don't match.
For example, I set the RILIM = 240kohm(F)
I got the following value Ios,when I use equation 1.
Ios,min = 340mA,Ios,typ = 402mA, Ios,max = 472mA
I got the following value Ios,when I use Fig.18.
Ios,min = 450mA,Ios,typ = 500mA, Ios,max = 550mA
so,I measured about current-limit threshold in our circuit.
<measurement condition>
RILIM = 240k(F), Vout = 3.3V
Ios = 480mA.
Please refer to attached waveform.
1ch : Vout, 4ch:Iout
