3 Description
The TPS20xxC and TPS20xxC-2 dual power-
distribution switch family is intended for applications
such as USB where heavy capacitive loads and
short-circuits may 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 dual 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 overcurrent
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.
2 Applications
• USB Ports or Hubs, Laptops, Desktops
