These devices offer a programmable current-limit threshold between 250 m A 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. Each channel of the TPS2561A-Q1 devices limits the output current to a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold. The FAULTx logic output for each channel independently asserts low during overcurrent and over temperature conditions. Use with the TPS2511-Q or TPS2513A-Q1 for a low loss, automotive qualified, USB Charging Port Solution capable of charging all of today's popular phones and tablets.
