Hi,
Datasheet appears to have contradicting information regarding current limit behaviour for R(lim) = Open and Short:
Table 5 tells I(OL_R-OPEN) is 15.5mA(typ) and I(OL_R-SHORT) is 39.3mA.
Figure 18 shows R(lim)=OPEN around 40mA, and R(lim)=SHORT around 15mA.
This figures are contadicting and it seems that figure 18 has the correct information.
Regards
