TPS3422EGDRYR

TPS3422EGDRYR is a single-button reset timer in a tiny 1.45x1.0 mm SON-6 (DRY) package, built to turn a mechanical push-button press into a clean, fixed 400 ms (typical) reset pulse. The input delay is selectable between two states, so one device supports both shorter and longer press behaviour, quiescent current is only 250 nA, the output is active-low open-drain, and operation spans 1.6 V to 6.5 V and -40 C to +125 C. For wearables, handhelds and sealed products, that gives a reliable factory-reset or recovery action without dedicating MCU resources to debouncing and timing, and the nanopower draw does not erode standby life. Selection advice: choose the EG timing option when the fixed 400 ms pulse and the two-state input delay match your user-interface plan; if the product needs a different pulse width or must handle multiple buttons, review the family's other timing options before committing the footprint.
