Description
General part information
TPS2068E Series
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 fixed current-limit thresholds for applications requiring 1.5A or 2A loading, with options between high or low enable polarization in different packages.
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 2.7V – 5.5V 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.
