我在做一个USB开发时，参考别人的电路，上面有用到一个芯片LM3526-L，用来起保护作用
我看这个芯片的datasheet时，看到电流保护时这样说的：
The current limit circuit is designed to protect the system
supply, the MOSFET switches and the load from damage
caused by excessive currents. The current limit threshold is
set internally to allow a minimum of 500 mA through the
MOSFET but limits the output current to approximately 1.0A
typical.
芯片的内部结构及应用如下图：
