DescriptionThe TPS20xxC and TPS20xxC-2 power-distribution
switch familyis intended for applications, such as
USB, where heavy capacitive loads and short circuits
are likely to be encountered. This family offers
multiple devices with fixed current-limit thresholds for
applications from 0.5Ato2A.
The TPS20xxC and TPS20xxC-2 family limits
output current toa safe level by operating
constant-current mode when the output load exceeds
the current limit threshold. This providesa predictable
fault current under all conditions. The fast overload
response time eases the burden on the main 5-V
supplyto provide regulated power when the outputis
shorted. The power-switch rise and fall times are
controlledto minimize current surges during turnon
and turnoff.
