Product Summary
The TPS2560DRCT is a dual-channel power-distribution switch intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. The device offers a programmable current-limit threshold between 250 mA and 2.8 A (typ) per channel via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. The applications of the TPS2560DRCT include USB Ports/Hubs, Digital TV, Set-Top Boxes, VOIP Phones.
