Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

These devices 0.15-1.5A Adjustable Current Limit contain 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 <2A Shutdown Current the output voltage is higher than the input voltage. Switch control is by a logic input (ON) capable of interfacing directly Auto Restart with low voltage control signals. Each part contains thermal Fast Current limit Response Time shutdown protection which shuts off the switch to prevent 5s 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, if the constant current condition still persists after 30ms, these Applications parts will shut off the switch and pull the fault signal pin (FLAGB) 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 turn off after a current limit fault, but will rather remain in the MP3 Players constant current mode indefinitely. The minimum current limit is Digital Cameras 150mA. Peripheral Ports These parts are available in a space-saving 6 pin 2X2 MLP Hot Swap Supplies package.
