FT7521  
Reset Timer with Fixed Delay and Reset Pulse  
Description  
Features  
The FT7521 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.

Fixed Reset Delay: 7.5 Seconds  
One Input Reset Pin  
Open-Drain Output Pin with Fixed 400ms Pulse  
1.8 V to 5.0 V Operation (TA=-40°C to +85°C)  
1.7 V to 5.0 V Operation (TA=-25°C to +85°C)  
1.65 V to 5.00 V Operation (TA=0°C to +85°C)  
<1 µA ICCQ Consumption  
The FT7521 has one input for single-button resetting  
capability. The device has a single open-drain output  
with 0.5 mA pull-down drive.  
FT7521 draws minimal ICC current when inactive and  
functions over a power supply range of 1.65 V to 5.0 V.
