DESCRIPTION
The Si4720CY 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 Si4720CY is available in a 16-pin SOIC package and is
rated for the commercial temperature range of –25 to 85_C.
