FPF2165R Datasheet PDF - ON Semiconductor

●The FPF2165R is a load switch that provides full protection to systems and loads which may encounter large current conditions. These devices contain a 0.12Ω current-limited Pchannel 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.When the switch current reaches the current limit, the parts operate in a constant-current mode to prohibit excessive currents from causing damage. The FPF2165R will not turn off after a current limit fault, but will rather remain in the constant current mode indefinitely. The minimum current limit is 150mA. These parts are available in a space-saving 6 pin 2X2 MLP package.
