DESCRIPTION
Si9717
Vishay Siliconix
The 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 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.
