The power-switch • Operating Range: 2.5 V to 6.5 V rise and fall times are controlled to minimize current • 2- μA Maximum Standby Supply Current surges during turn on/off. • Built-in Soft-Start Each channel of the TPS2560/61 devices limit the • 15 kV / 8 kV System-Level ESD Capable output current to a safe level by switching into a constant-current mode when the output load exceeds • UL Listed – File No. E169910 the current-limit threshold. The FAULTx logic output • CB & Nemko Certified for each channel independently asserts low during overcurrent and over temperature conditions. APPLICATIONS • USB Ports/Hubs • Digital TV • Set-Top Boxes • VOIP Phones Figure 1.
