General Description
●The FPF2163, FPF2164, and FPF2165 is a series of load switches which provides full protection to systems and loads which may encounter large current conditions. These devices contain a 0.12Ωcurrent-limited P-channel MOSFET which can operate over an input voltage range of 1.8-5.5V. Internally, current is prevented from flowing when the MOSFET is off and the output voltage is higher than the input voltage. Switch control is by a logic input (ON)capable of interfacing directly
●with low voltage control signals. Each part contains thermal shutdown protection which shuts off the switch to prevent damage to the part when a continuous over-current condition causes excessive heating.
