The TPS2551 power-distribution switch is intended for applications in which heavy capacitive loads and short circuits are likely to be encountered, incorporating a 100-mΩ, N-channel MOSFET in a single package. The current-limit threshold is user adjustable between 100  mA and 1.1  A via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during switching.

The device limits the output current to a desired level by switching into a constant-current mode when the output load exceeds the current-limit threshold or a short is present. An internal reverse-voltage detection comparator disables the power-switch in the event that the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT logic output asserts low during both overcurrent and reverse-voltage conditions.
