      CXES4294集成了两个独立的低漏失的线性开关，每路开关都具有开/关控制、输出电流软启动和输出限流的功能.应用时，将CXES4294连接至降压DC/DC的输出端，使能引脚控制每路开/关以最大效率来传递电压。因此，CXES4294能延长电池的寿命和工作时间。当EN引脚接低电压时，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。可以利用外部可编程的软启动功能来设置上电时序，以避免启动阶段的输入电流过冲。CXES4294还包括了过流和过热保护功能。The CXES4294 contains two independent low dropout line switches with ON/OFF control, output current soft-start and output current protection. By connecting the CXES4294 to the output pins of two step-down DC/DC converters, the EN1/EN2 pins control ON/OFF for each distribution switch to deliver power per requirements and maximize total power efficiency. As a result, the CXES4294 helps to same system power and extend battery life. When a low signal is inputted to the EN pin, each switch enters shutdown mode. Even 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. Externally programmable soft-start allows proper power on sequencing with respect to other power supplies and avoids input inrush current during startup. Other features include current limit protection and thermal shutdown protection
