Description
The FT7511 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 FT7511 has one input for single-button resetting
capability. The device has a single open-drain output
with 0.5mA pull-down drive.
FT7511 draws minimal ICC current when inactive and
functions over a power supply range of 1.65V to 5.0V.
