    CXES4295是一款低漏失，将PMOS集成于IC内部的线性开关，它具有开/关控制功能和输出电流保护功能.应用时，将CXES4295连接至降压DC/DC的输出端，CXES4295的使能引脚控制每路开/关以最大效率的传递电压。因此，CXES4295能延长电池的寿命和工作时间。CXES4295的功能包括了电流限制保护电路，不需要在芯片外部增加额外的电阻和MOSFET来实现此功能。外部可编程软启保证了正确的启动时序，以防止输入电流在启动过程中的过冲。当EN引脚为低电压时，IC进入关断模式。此时，即使芯片的输出端连接容性负载，电容负载上存储的电荷也会被内部的放电开关快速放电至地，从而，输出VOUT的电压也会快速下降到地。CXES4295包括了过热保护功能。The CXES4295 is a low dropout line switch IC with ON/OFF control and output current protection which integrates a P-channel MOSFET. By connecting the CXES4295 to the output pin of a step-down DC/DC converter, the EN pin controls ON/OFF for each distribution switch to deliver power per requirements and maximize total power efficiency. As a result, the CXES4295 helps to extend battery life and product operation time. The CXES4295 contains a current limit protection circuit so these are not required externally unlike discrete circuit solutions where MOSFETs and resistors are used. Externally programmable soft-start allows for proper power on sequencing with respect to other power supplies and avoids input inrush current during startup. When a low signal is input to the EN pin, the IC enters shutdown mode. Even where a load capacitor is connected to the output pin during shutdown, the electric charge stored at the load capacitor is discharged through the internal switch. As a result, the VOUT pin voltage falls quickly to the GND level. The CXES4295contains thermal shutdown protection.
