Product Summary
The TPS2551DBVR power-distribution switch is intended for applications where 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 of TPS2551DBVR 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 applications of the TPS2551DBVR include USB Ports/Hubs, Cell phones, Laptops, Heavy Capacitive Loads, Reverse-Voltage Protection.
