Part Details:

FPF2163/4/5 Full Fun October 2007 FPF2163/4/5 tm Full Function Load Switch with Adjustable Current Limit Features General Description cti 1.8 to 5.5V Input Voltage Range The FPF2163, FPF2164, and FPF2165 is a series of load on Load Switch with Adju Controlled Turn-On switches which provides full protection to systems and loads 0.15-1.5A Adjustable Current Limit which may encounter large current conditions. These devicescontain a 0.12 current-limited P-channel MOSFET which can Undervoltage Lockout operate over an input voltage range of 1.8-5.5V. Internally, Thermal Shutdown current is prevented from flowing when the MOSFET is off and <2µA Shutdown Current the output voltage is higher than the input voltage. Switch Auto Restart control is by a logic input (ON) capable of interfacing directly Fast Current limit Response Time with low voltage control signals. Each part contains thermalshutdown protection which shuts off the switch to prevent 5µs to Moderate Over Currents damage to the part when a continuous over-current condition 30ns to Hard Shorts causes excessive heating. Fault Blanking When the switch current reaches the current limit, the parts Reverse Current Blocking operate in a constant-current mode to prohibit excessive RoHS Compliant currents from causing damage. For the FPF2163 and FPF2164, st if the constant current condition still persists after 30ms, theseparts will shut off the switch and pull the fault signal pin (FLAGB) able Current Limit Applications low. The FPF2163 has an auto-restart feature which will turn the PDAs switch on again after 450ms if the ON pin is still active. The Cell Phones FPF2164 does not have this auto-restart feature so the switch GPS Devices will remain off until the ON pin is cycled. The FPF2165 will not MP3 Players turn off after a current limit fault, but will rather remain in the Digital Cameras constant current mode indefinitely. The minimum current limit is150mA. Peripheral PortsHot Swap Supplies These parts are available in a space-saving 6 pin 2X2 MLPpackage. Pin 1 BOTTOM
