FPF2174 − IntelliMAX™ Advanced Load Management Products
The FPF2174 is a load switch which combines the functionality of the IntelliMAXTM series load switch with a very low forward voltage drop Schottky barrier rectifier and a zener clamp at the output. The integrated solution provides full protection to systems and loads which may encounter large current conditions in a very compact MLP 3x3 package. This device contain a 0.125Ω current-limited P-channel MOSFET which can operate over an input voltage range of 1.8-5.5V. The Schottky diode acts as a barrier so that no reverse current can flow 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 part operates in a constant-current mode to prohibit excessive currents from causing damage. If the constant current condition still persists after 10ms, these parts will shut off the switch and pull the fault signal pin (FLAGB) low. The switch will remain off until the ON pin is cycled. The minimum current limit is 200mA. These parts are available in a space-saving 6L MLP 3x3 package.
