3 Description
The TPD3S014-Q1 is an integrated device that
features a current-limited load switch and a two-
channel transient voltage suppressor (TVS) based
electrostatic discharge (ESD) protection diode array
for USB interfaces.
The TPD3S014-Q1 device is intended for applications
such as USB where heavy capacitive loads and
short-circuits are likely to be encountered; the
TPD3S014-Q1 provides short-circuit protection and
overcurrent protection. The TPD3S014-Q1 limits the
output current to a safe level by operating in constant
current mode when the output load exceeds the
current limit threshold. The fast overload response
eases the burden on the main 5 V power supply by
quickly regulating the power when the output is
shorted. The rise and fall times for the current limit
switch are controlled to minimize current surges when
turning the device on and off.
The TPD3S014-Q1 allows 0.5 A of continuous
current. The TVS diode array is rated to dissipate
ESD strikes above the maximum level specified in the
IEC 61000-4-2 international standard.
The high level of integration, combined with its easy-
to-route DBV package, allows this device to provide
great circuit protection for USB interfaces in
applications like head units, USB hubs, and media
interfaces.
