FPF2165R Full Function Load Switch with Adjustable Current Limit April 2009 FPF2165R Full Function Load Switch with Adjustable Current Limit Features - 1.8 to 5.5V Input Voltage Range - Controlled Turn-On - 0.15-1.5A Adjustable Current Limit - +/- 10% Current Limit Accuracy versus Temperature - Undervoltage Lockout - Thermal Shutdown - <2µA Shutdown Current - Fast Current limit Response Time - 5µs to Moderate Over Currents - 30ns to Hard Shorts - Reverse Current Blocking - RoHS pliant tm General Description The FPF2165R is a load switch which 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. Applications - PDAs - Cell Phones - GPS Devices - MP3 Players - Digital Cameras - Peripheral Ports - Hot Swap Supplies ..
