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 integrated solution provides full protection to 200 mA Current Limit Option systems and loads which may encounter large current Under-Voltage Lockout (UVLO) conditions in a very compact MLP 3 x 3 package. This device contains a 0.125 current-limited P-channel Thermal Shutdown MOSFET which can operate over an input voltage range <1 A Shutdown Current of 1.8-5.5 V. The Schottky diode acts as a barrier so that no reverse current can flow when the MOSFET is Fast Current Limit Response Time: off and the output voltage is higher than the input 3 s to Moderate Over Currents voltage. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signals. 20 ns to Hard Shorts Each part contains thermal shutdown protection which Integrated very Low VF Schottky Diode for Reverse shuts off the switch to prevent damage to the part when Current Blocking a continuous over-current condition causes excessive heating. RoHS Compliant When the switch current reaches the current limit, the part operates in a constant-current mode to prohibit Applications excessive currents from causing damage. If the constant current condition still persists after 10 ms, PDAs these parts will shut off the switch and pull the fault Cell Phones signal pin (FLAGB) low. The switch will remain off until the ON pin is cycled. The minimum current limit is GPS Devices 200 mA. MP3 Players These parts are available in a space-saving 6-lead MLP Digital Cameras 3 x 3 package.
