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 long delay One Input Reset Pin helps avoid unintended resets caused by accidental key presses. It has a fixed delay of 7.5 20% seconds. The Open-Drain Output Pin with Fixed 400ms Pulse DSR pin enables Test Mode operation by immediately forcing /RST1 LOW for factory testing. 1.8V to 5.0V Operation (T =-40C to +85C) A The FT7522 has one input for single-button resetting 1.7V to 5.0V Operation (T =-25C to +85C) A capability. The device has a single open-drain output 1.65V to 5.0V Operation(T =0C to +85C) A with 0.5mA pull-down drive. <1A I Consumption CCQ FT7522 draws minimal I current when inactive and CC Zero-Second Test-Mode Enable functions over a power supply range of 1.65V to 5.0V.
