RT9702PB

RT9702全新原装现货，***赔十13724201506李生，***2629331408.The RT9702 and RT9702A are cost-effective, low voltage, single N-Channel MOSFET high-side power switches, optimized for self-powered and bus- powered Universal Serial Bus (USB) applicati***. The RT9702/A equipped with a charge pump circuitry to drive the internal MOSFET switch; the switch's low ***(ON), 80mΩ, meets USB voltage drop requirements; and a flag output is ***ailable to indicate fault conditi*** to the local USB controller.
Additional features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present, fault current is limited to typically 800mA for RT9702 in single port and 1.5A for RT9702A in dual ports in accordance with the USB power requirements, lower quiescent current as 25μA making this device ideal for portable battery-operated equipment.
The RT9702/A is ***ailable in SOT-23-5 and TSOT-23-5 packages requiring minimum board space and ***allest components.

SOT-23-5/TSOT-23-5

Note: A low-ESR 150μF aluminum electrolytic or tantalum between VOUT and GND is strongly recommended to meet the330mV maximum droop requirement in the hub VBUS. (see Application Information Section for further details)
