Fairchild Reset Timers with Fixed
or Configurable Delay

Fairchild's FT1001/FT3001/FT7522 Reset Timers with Fixed or Configurable Delay are timers for resetting a mobile device where long reset times are needed. The FT7522 and FT1001 provide fixed delays of 7.5 and 10 seconds and offer inputs for single-button resetting capability. The FT3001 provides design flexibility with two inputs for single- or dual-button resetting capability as well as four different delay values that can be selected by configuring the DSR0 and DSR1 pins. All of the devices function over a power supply range of 1.65V to 5.0V and draw minimal supply current when inactive, making them suitable for use in portable devices where battery conservation is essential.
