TPS2561DRCR Description
TPS2561DRCR is a kind of precision adjustable power switch with two separate current limiting channels. When the output load exceeds the current-limit threshold, each channel is able to limit the output current to a safe level by switching into a constant-current mode. It is specifically designed for applications requiring precision current limiting or applications where heavy capacitive loads and short circuits are encountered. The power-switch rise and fall times can be controlled so as to minimize current surges during turn on and off.
