FP6862
Dual-Channel U8S5BT
High-Side Power Switch
Description
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.
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.
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.
