General Description
The FPF2148 is a load switch which provides full protection to systems and loads which may encounter large current conditions. These devices contain a 0.12Ω current-limited P-channel MOSFET which can operate over an input voltage range of 1.8-5.5V. Switch control is by a logic input (ONB) capable of interfacing directly with low voltage control signals. The part contains thermal shutdown protection which shuts off the switch to prevent damage.
