3 Description
The TPS20xxE 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 1.5
A to 2 A.
The TPS20xxE 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 3.3-V–5.5-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.
