Vishay Siliconix
Battery Disconnect Switch
Level-Shifted Gate Drive with Internal MOSFET
Ultra Low Power Consumption in Off State
(Leakage Current Only)
Logic Supply Voltage is Not Required
Solution for Bi-Directional Blocking
Bi-Directional Conduction Switch
6- to 30-V Operation
Ground Referenced Logic Level Inputs
Integrated Low rDS(on) MOSFET
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 85C.
