LM5118 UVLO current source characteristics

In trying to accurately calculate a worst-case range of UVLO thresholds for a given resistor divider pair, the UVLO current source needs to be taken into account.  However, I only see a typical 5uA value specified at a UVLO pin voltage of zero.  If additional information is available:

1) Is there any sort of expected tolerance on that 5uA value over temperature?

2) Since the 5uA value is specified for a UVLO pin voltage of zero, does that current go down as the UVLO pin voltage rises?  If so, at what rate would it approximately go down?

Thanks

  • Hi 

    The tolerance of 5uA current will be most likely about +/-30%, but unfortunately it has not been characterized. The current is only important at the threshold and should not vary much between 0V and 1.231V.
