TPS2560DRCR Description

The TPS2560DRCR is a dual-channel power-distribution switch designed for use in situations where precise current limitation is necessary, as well as those involving significant capacitive loads and short circuits. Through an external resistor, these devices provide a configurable current-limit threshold between 250 mA and 2.8 A (typ) per channel. The rise and fall times of the power switch are regulated to reduce current surges during turn-on and turn-off.

When the output load exceeds the current-limit threshold, each channel of the TPS2560DRCR device limits the output current to a safe level by switching into a constant-current mode. Each channel's FAULTx logic output independently asserts low when there is an overcurrent or temperature problem.
