the fp6861e-c/e/f/h is a cost-effective, low voltage, single n-channel mosfet high-side power switch, optimized for self-powered and bus-powered universal serial bus (usb) applications.
the fp6861e-c/e/f/h 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 fp6861e-c/e/f/h in single port in accordance with the usb power requirements. fp6861e-c/e/f/h will prevent reverse current when it is disabled and vout is higher than vin.
the fp6861e-c/e/f/h is available in msop-8, sop-8 and sot-23-5 packages with smallest components.
