generation capability via the C
capacitor to GND. This evaluation platform has an adjustable
SMD capacitor, C4 (8pF to 45pF) that allows easy evaluation
of this feature. Also unique to the ISL88707 and ISL88708
are both the RESET and RESET outputs, all other variants
having only one or the other.
Figures 10, 11, 12, 13 and 14 illustrate the basic IC functions
and performance of the 3 implementations.
