CXUS7702

CXUS7702是一款低电压、高性能的单N-MOSFET功率开关,专为具有低RDS(on)≈70mΩ和全保护功能的电源轨开/关控制而设计。CXUS7702配有一个电荷泵电路,用于驱动内部MOSFET开关和一个标志输出,用于指示针对大di/dt的故障情况,这可能导致电源失去调节。为了适应不同的应用,提供了一个ISET引脚来设置电流限制点,一个ISET到接地的电阻来设置开关的电流限制。附加功能包括软启动以限制插入期间的涌入电流,热关机以防止大电流负载导致灾难性开关故障,输出防回流保护(无论EN-pin连接的是GND还是VIN),欠压锁定(UVLO)确保设备保持关闭,除非存在有效的输入电压,精密电阻可编程输出电流限制高达3.5A。此外,较低的静态电流为40μa,使该设备成为便携式电池操作设备的理想选择。

   产品概述 返回TOPWuZ嘉泰姆


The CXUS7702 is a low voltage, high performance single N-MOSFET power switch, designed for power rail on/off control with low RDS(ON)≈70mΩ and full protection functions. The CXUS7702 equipped with a charge pump circuitry to drive the internal MOSFET switch and a flag output is available to indicate fault conditions against large di/dt which may cause the supply to fall out of regulation. In order to fit different application, an ISET pin is offered for current limit point setting, a resistor from ISET to ground sets the current limit for the switch. Additional features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, Output anti back irrigation Protection whether EN pin is connected GND or VIN, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present, a precision resistor-programmable output current limit up to 3.5A. Besides, the lower quiescent current as 40μA making this device ideal for portable battery-operated equipment. 

The CXUS7702 is available in SOT23-5 or SOP-8 package requiring minimum board space and smallest components.
