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.

The input Typical R = 250m V = 5.5V DS(ON) IN voltage range operates from 1.8V to 5.5V to fulfill today s Ultra Typical R = 275m V = 3.3V DS(ON) IN Portable Device s supply requirement. Switch control is by a 100-250mA (min) Adjustable Current Limit logic input (ON) capable of interfacing directly with low voltage 5% Current Limit Tolerance 250mA (min) control signal. On-chip pull-down is available for output quick 72 (typ) Output Discharge Resistance discharge when switch is turned off. ESD Protected, Above 8000V HBM and 2000V CDM For the FPF2214, if the constant current condition still persists after 30ms, these parts will shut off the switch and pull the fault Applications signal pin (FLAGB) low. The FPF2213 has an auto-restart feature, which will turn the switch on again after 450mS if the PDAs ON pin is still active. The FPF2214 do not have this auto-restart Cell Phones feature so the switch will remain off until the ON pin is cycled. GPS Devices For the FPF2215, a current limit condition will immediately pull MP3 Players the fault signal pin low and the part will remain in the constant- current mode until the switch current falls below the current Digital Cameras limit. For the FPF2213 through FPF2215, the current limit is set Peripheral Ports by an external resistor and the minimum current limit is 100mA.
