FPF2104集成电路（IC）的配电开关负载驱动器规格书PDF中文资料

General Description

The FPF2100 through FPF2107 is a family of load switches which provide full protection to systems and loads which may encounter large current conditions. These devices contain a 0.125Ω 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 (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.
