DescriptionThe TPS2560 and TPS2561 are dual-channel power-
distribution switches intended for applications where
precision current limiting is required or heavy
capacitive loads and short circuits are encountered.
These devices offera programmable current-limit
threshold between 250 mA and 2.8A (typ) per
channel through an external resistor. The power-
switch rise and fall times are controlledto minimize
current surges during turnon and off.
Each channelof the TPS256x devices limit the output
currenttoa safe level by switching intoa constant-
current mode when the output load exceeds the
current-limit threshold. The FAULTx logic output for
each channel independently asserts low during
overcurrent and overtemperature conditions.
