General Description

The TPS2560 and TPS2561 (TPS256x) are dualchannel power-distribution switches intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered.

These devices offer a programmable current-limit threshold between 250 mA and 2.8 A (typ) per channel through an external resistor.

The power-switch rise and fall times are controlled to minimize current surges during turn on and off.
