TPS2553DBVT Datasheet

Power Switch ICs - USB


The TPS2552/ TPS2553DBVT and TPS2552-1/53-1 power-distribution switches are 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 75 mA and 1.3 A (typ) via an external resistor. Current-limit accuracy as tight as +/-6% can be achieved at the higher current-limit settings. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. TPS2553DBVT Features • ±6% Current-Limit Accuracy at 1.3 A• Meets USB Current-Limiting Requirements• Backwards Compatible with TPS2550/51• Adjustable Current Limit, 75 mA–1300 mA (typ)• Fast Overcurrent Response - 2-mS (typ)• 85-mΩ High-Side MOSFET (DBV Package)• Reverse Input-Output Voltage Protection TPS2553DBVT Applications • USB Ports/Hubs• Digital TV• Set-Top Boxes• Mobile Phones• VOIP Phones
