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. When the switch current reaches the current limit, the part operates in a constant-current mode to prohibit excessive currents from causing damage. For the FPF2100-FPF2102 and FPF2104-FPF2106, if the constant current condition still persists after 10ms, these parts will shut off the switch an
