FP6861D
Dual-Channel
Power Distribution Switch
Description
The FP6861D is a cost-effective, low voltage, dual
N-Channel MOSFET high-side power switch,
optimized for self-powered and bus-powered
Universal Serial Bus (USB) applications.
The FP6861D 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 FP6861D in dual port in
accordance with the USB power requirements.
FP6861D will prevent reverse current when it is
disabled and VOUT is higher than VIN.
The FP6861D is available in SOP-8 package with
smallest components.
