The WP6420 circuit use N channel lateral MoSas POWER FET embedded protection functionswhich consist of thermal-shutdown circuit，currentlimitation circuit,Overload protection circuit andshort circuit protection. When the circuit is shortcircuited，current limitation circuit is firstly triggeredand a high current flow through POWER FET whichled to high temperature of POWER FET.And thenthe thermal-shutdown circuit is triggered to shutdown the circuit. So the current limitation circuit andthermal-shutdown circuit act as the short circuitprotection role.

     WP6420电路采用N通道横向MOSAS功率场效应管嵌入式保护功能，包括热关机电路、电流限制电路、过载保护电路和短路保护电路。当电路短路时，首先触发限流电路，大电流流过功率场效应管，导致功率场效应管高温，然后触发热关断电路关闭电路。因此，限流电路和热停电路起着短路保护的作用.

     The WP6420 circuit features low on resistance,considerable load current. The input voltage canvary from 0V to 10V.The device is available in sOT-223 package.

     WP 6420电路具有低的电阻，相当大的负载电流。输入电压可以在0V到10V之间变化，器件可以在St-223封装中使用。
