TPS2559-Q1 Power-Distribution Switch

Texas Instruments TPS2559-Q1 Current-Limited Power-Distribution Switch is intended for applications where a low resistance, the precision current limit switch is required or heavy capacitive loads are encountered. The TPS2559-Q1 provides up to 5.5A of continuous load current with a precise current limit set by a single resistor to ground. The output current is maintained at a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold. During overload events, the output current is limited to the level set by R_(ILIM). If a persistent overload occurs, the device goes into thermal shutoff to prevent damage to the TPS2559-Q1.
