DESCRIPTION
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.
The Si9717 is available in both standard and lead (Pb)-free
packages.
