VGG_CAP
VGG_CAP is a charge storage connection for the internal charge pump
of the SMS64. This capacitor should be of sufficient size so as to provide
current, under varying load conditions, to the PUP outputs that are
programmed as high side drivers. For most applications this can be tied to a
01
µF capacitor.

The points of use power enable (PUP) outputs are used when cascading
or sequencing external supplies such as LDO’s DC-to-DC converters or
MOSFETs.
The output can be configured as an open drain active high or active low
output. In both configurations an external pull-up resistor is required.
The output can also be configured as a high-side driver output. The
output voltage for this configuration can be set at 10.5V or 14.5V.
