DESCRIPTION
The Si9717CY is a reverse blocking switch for battery
disconnect applications. It is an integrated solution for multiple
battery technology designs or designs that require isolation
from the power bus during charging. The Si9717CY is
available in a 16-pin SOIC package and is rated for the
commercial temperature range of 0 to 70擄C.
