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.

This device contains a 0.125 current-limited P- 200mA Current Limit channel MOSFET which can operate over an input voltage Undervoltage Lockout range of 1.8-5.5V. Internally, current is prevented from flowing Thermal Shutdown when the MOSFET is off and the output voltage is higher than <2A Shutdown Current the input voltage. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signals. Auto Restart The part contains thermal shutdown protection which shuts off Fast Current limit Response Time the switch to prevent damage to the part when a continuous 3s to Moderate Over Currents over-current condition causes excessive heating. 20ns to Hard Shorts When the switch current reaches the current limit, the part Fault Blanking operates in a constant-current mode to prohibit excessive Reverse Current Blocking currents from causing damage. If the constant current condition RoHS Compliant still persists after 30ms, the part will shut off the switch and pull the fault signal pin (FLAGB) low. An auto-restart feature will turn Applications the switch on again after 480ms if the ON pin is still active. The minimum current limit is 200mA. PDAs The part is available in a space-saving 5 pin SOT23 package.
