DESCRIPTION
The Si4710CY is a level-shifted p-channel MOSFET. Operating
two in a series, 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 Si4710CY is available in a 8-pin SOIC package and is rated
for the commercial temperature range of –25 to 85_C.
