FT7522: Reset Timer with Fixed Delay and Reset Pulse

The FT7522 is a timer for resetting a mobile device where long reset times are needed. The long delay helps avoid unintended resets caused by accidental key presses. It has a fixed delay of 7.5 ±20% seconds. The DSR pin enables Test Mode operation by immediately forcing /RST1 LOW for factory testing.

The FT7522 has one input for single-button resetting capability. The device has a single open-drain output with 0.5mA pull-down drive.

FT7522 draws minimal ICC current when inactive and functions over a power supply range of 1.65V to 5.0V.
