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 between 0.5 A and 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 turn-on
and turn-off.
