3 Description
The TPS20xxC and TPS20xxC-2 power-distribution
switch family is 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 0.5 A to 2 A.
The TPS20xxC and TPS20xxC-2 family 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 5-V
supply to provide regulated power when the output is
shorted. The power-switch rise and fall times are
controlled to minimize current surges during turnon
and turnoff.
