Description
The FT3001 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. Four timer values can be selected by hard-
wiring the DSR0 and DSR1 pins.
The FT3001 has two inputs for single- or dual-button
resetting capability. The device has two outputs: a push-
pull output with 0.5 mA drive and an open-drain output
with 0.5 mA pull-down drive.
The FT3001 draws minimal supply current when
inactive and functions over a power supply range of
1.65 V to 5.0 V.
