SI4720CY

Si4720CY Vishay Siliconix Battery Disconnect Switch FEATURES D Solution for Bi-Directional Blocking Bi-Directional Conduction Switch D 6- to 30-V Operation D Ground Referenced Logic Level Inputs D Integrated Low rDS(on) MOSFET D Level-Shifted Gate Drive with Internal MOSFET D Two Independent Inputs D Ultra Low Power Consumption in Off State (Leakage Current Only) D Logic Supply Voltage is Not Required 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.
