Si4710CY New Product 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. 2 IN 1 5, 6, 7 ESD GND Logic and Gate Drive G D Level Shift 8 VGS Limiter 3, 4 S Half a circuit shown here.
