USB限流芯片,可调最大限流点0.5A--2A之间,SOT23-5封装。适用于多口充电产品,单口限流保护输出产品。

PL2700特点:

输入电压范围:2.4V --5V

快速瞬态响应:<2μs

热拔插软启动

内置80MΩ低内阻MOS管

反向电流阻断

功耗:

VIn=5V,EN脚悬空,功耗0.1uA

VIn=5V,EN脚连接,功耗15uA

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.
