AN-1002 Reverse Current Blocking with Silego GreenFET Load Switches
There are many power management applications using MOSFETs that require no reverse current leakage when controlling a power rail. Due to the nature of a MOSFET, the body diode can conduct current when the source voltage is higher than the drain voltage (the MOSFET is OFF). This condition prevents the MOSFET from blocking any reverse current causing an undesirable design behavior. Using two Silego GreenFET family load switches back-to-back prevents this condition from occurring and provides many features that make designers life much easier. Some of these features are low RDS(on) resistance, slew rate control, inrush current management, over-current, over-voltage and thermal protection.
