代理PL2700  USB限流开关IC  

PL2700，可调限流0.5A-2A，
PL2702，可调限流1A-3A，带短路保护。   跟PL2700脚位PIN对PIN 

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 rangingfrom2.4Vto5.5V,makingitideal 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 1μA.The PL2700 is 5 package.
