Battery Disconnect Switch
Si4720
Vishay Siliconix
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 °C to
85 °C.
FEATURES
• Solution for Bi-Directional Blocking
• 6 V to 30 V Operation
• Ground Referenced Logic Level Inputs
• Integrated Low R_DS(on) MOSFET
• Level-Shifted Gate Drive with Internal MOSFET
• Two Independent Inputs
• Ultra Low Power Consumption in Off State
(Leakage Current Only)
• Logic Supply Voltage is Not Required
