These devices offer a programmable current-limit threshold between • Adjustable Current Limit, 250 mA–2.8 A (typ) 250 mA and 2.8 A (typ) per channel through an • ± 7.5% Current-Limit Accuracy at 2.8 A external resistor. The power-switch rise and fall times • Fast Overcurrent Response - 3.5- μS (typ) are controlled to minimize current surges during turn on or off. • Two 44-m Ω High-Side MOSFETs • Operating Range: 2.5 V to 6.5 V Each channel of the TPS2561-Q1 device limits the output current to a safe level by switching into a • 2- μA Maximum Standby Supply Current constant-current mode when the output load exceeds • Built-in Soft-Start the current-limit threshold. The FAULTx logic output • 15 kV or 8 kV System-Level ESD Capable for each channel independently asserts low during overcurrent and over temperature conditions. • UL Listed – File No. E169910 • CB and Nemko Certified Figure 1.
