The TPS2552D and TPS2553D power-distribution switches are intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered and provide up to 1.5 A of continuous load current.
These devices offer a programmable current-limit threshold between 75 mA and 1.7 A (typ) via an external resistor. Current-limit accuracy as tight as±6% can be achieved at the higher current-limit settings. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. The TPS2552D/3D devices limit the output current to a safe level by using a constant-current mode when the output load exceeds the current-limit threshold.
An internal reverse-voltage comparator disables the power-switch when the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT output asserts low during overcurrent and reverse-voltage conditions.
