   产品概述 返回TOPpXD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.
