The PL2700 is a cost-effective, low voltage,single P-MOSFET load switch,optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. This switch operates with inputs ,-itideal forboth 3V and 5V s The switch's low RDS(ON), 80mΩ ,meets USB voltage drop requirements. The PL2700 is also protected from thermal overload which limits power dissipation and junction temperatures. Current limit threshold is programmed with a resistor from SET to ground. The quiescent supply current is typically 15μA at switch on state. At switch off state the supply current decreases to less than 1μ PL2700 is 5 PACkage.
