Description
General part information
TPS2559-Q1 Series
The TPS2559-Q1 power-distribution switch is intended for applications where a low resistance, precision current limit switch is required or heavy capacitive loads are encountered. The TPS2559-Q1 provides up to 5.5 A of continuous load current with a precise current limit set by a single resistor to ground. 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.
The power-switch rise and fall times are controlled to minimize current surges during turn on or off. TheFAULTlogic output asserts low during overcurrent or overtemperature conditions.
