FP6861D

Dual-Channel

Power Distribution Switch

Description

Features

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.

● Compliant to USB Specifications

● Built-In Low RDS(ON) N-Channel MOSFET

● Output Can Be Forced Higher Than Input

(Off-State)

● Low Supply Current:

The FP6861D is equipped with a charge pump

circuitry to drive the internal MOSFET switch. The

switch's low R_DS(ON)meets USB voltage drop

requirement, and a flag output is available to indicate

fault conditions to the local USB controller.

130μA Typical at Switch On State

0.2μA Typical at Switch Off State

● Wide Input Voltage Ranges: 2.7V to 5.5V

● Open-Drain Fault Flag Output

● Hot Plug-In Application (Soft-Start)

● 2.2V Typical Under-Voltage Lockout (UVLO)

● Current Limiting Protection

● Thermal Shutdown Protection

● Reverse Current Flow Blocking (No Body Diode)

● Logic Level Enable Pin

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.

● SOP-8 Package

● RoHS Compliant

● UL NO.E322418 (Approved model: FP6861 series)

Applications

● USB Bus/Self Powered Hub

● USB Peripheral

● ACPI Power Distribution

● Notebook, Motherboard PC

● Battery-Charger Circuit

The FP6861D is available in SOP-8 package with

smallest components.
