Dual-Channel USB
High-Side Power Switch
Description
Features
The FP6862 is dual high-side MOSFET switches
with independent enable and error flag functions,
optimized for general-purpose power distribution and
Universal Serial Bus (USB) requiring circuit
protection.
● 100mΩ (5V Input) On-Resistance Per Channel
● 2.7V to 5.5V Operating Range
● 1A Minimum Continuous Current Per Channel
● Short Circuit Protection with Thermal Shutdown
● Thermally Isolated Channels
● Under Voltage Lockout (UVLO)
● Reverse Current Flow Blocking
● Soft-Start Circuit
● Enable Active Low or Active High
● RoHS Compliant
The FP6862 supports the following USB
requirements: each switch channel supplies up to 1A
as required by USB downstream devices; the low on-
resistance switch meets the USB voltage drop
requirements.
Both switches employ soft-start circuit that minimizes
inrush current in applications where highly capacitive
loads are employed.
Applications
● USB Peripheral
● General Purpose Power Switching
● ACPI Power Distribution
● Notebook PC
A fault status output flag is asserted during over-
current, thermal shutdown or UVLO conditions.
Under voltage lockout (UVLO) to ensure that the
device remains off unless there is a valid input
voltage present and 3.3V or 5V logic compatible
enable single inputs.
● PDA
● PC Card Hot Swap
