Accurate 2.1A Min / 2.5A Max Setting Fast Short Circuit Response - 3.5-μs (typ) Two 44-mΩ High-Side MOSFETs Operating Range: 2.5 V to 6.5 V 2-μA Maximum Standby Supply Current Built-in Soft-Start 15 kV / 8 kV System-Level ESD Capable 2 Applications Automotive USB Charging Ports 3 Description The TPS2561A-Q1 is dual-channel power-distribution switch intended for automotive 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 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. 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 tempera...
