DESCRIPTION
The TPS2530 power-distribution switch is intended
for applications such as DisplayPort or USB Port
where heavy capacitive loads and short-circuits are
likely to be encountered. It offers 0.5 A fixed current-
limit thresholds.
The TPS2530 limits the output current to a safe level
by operating in a constant-current mode when the
output load exceeds the current-limit threshold. This
provides a predictable fault current under all
conditions. The fast overload response time eases
the burden on the main supply to provide regulated
power when the output is shorted. The power-switch
rise and fall times are controlled to minimize current
surges during turn-on and turn-off.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
