3 Description
The TPD3S0x4s are integrated devices that feature a
current-limited load switch and a two-channel
transient voltage suppressor (TVS) based
electrostatic discharge (ESD) protection diode array
for USB interfaces.
The TPD3S0x4 devices are intended for applications
such as USB where heavy capacitive loads and
short-circuits are likely to be encountered;
TPD3S0x4s provide short-circuit protection and
overcurrent protection. The TPD3S0x4s limit 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 and TPD3S044 will allow 0.5 A and
1.5 A of continuous current, respectively. 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 laptops, high-definition digital TVs,
set-top boxes, and electronic point of sale equipment.
