DESCRIPTION
The Si4719CY is two level-shifted p-channel MOSFETs.
Operating together, these MOSFETs can be used as a reverse
blocking switch for battery disconnect applications. It is a
solution for multiple battery technology designs or designs that
require isolation from the power bus during charging.
The Si4719CY is available in a 16-pin SOIC package and is
rated for the commercial temperature range of –25 to 85_C.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
