DESCRIPTION
The Si9718CY 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 Si9718CY is
available in a 16-pin SOIC package and is rated for the
commercial temperature range of 0 to 70°C.

Notes:
a. Room = 25°C, Full = as determined by the operating temperature suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Tested at room temperature, high temperature guaranteed by statistical data correlation techniques.
