1 For
input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.
2 For I G(HI) , V CP relative to V BB .
3 Minimum values of V Dx are specified only to avoid short-to-battery nuisance faults. For more information, refer to the Open Load Fault Level topic in
the Applications Information section.
4 Minimum and maximum not tested; guaranteed by design.
