Battery Disconnect Switch
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 mercial 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 RDS(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
