產品說明



the fp6861g is a low rds(on), low power loss, single n-channel mosfet high-side power switch, optimized for self-powered and bus-powered universal serial bus (usb) applications.
the fp6861g is equipped with a charge pump circuitry to drive the internal mosfet switch. the switch's low rds(on) meets usb voltage drop requirement, and a flag output is available to indicate fault conditions 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, and under-voltage lockout (uvlo) to ensure that the device remains off unless there is a valid input voltage present. besides, fault current is limited to specific current for fp6861g in single port in accordance with the usb power requirements. fp6861g will prevent reverse current when it is disabled and vout is higher than vin.
the fp6861g is available in fc-sot-23-5, sot-23-5 and msop-8 packages with smallest components.
