FT8010: Reset Timer with Configurable Delay

The FT8010 is a timer for resetting a mobile device where long reset times are needed. The long time delay helps avoid unintended resets caused by accidental key presses. Two delays can be selected by hard-wiring the DSR pin: 7.5 ±20% seconds or 11.25 ±20% seconds.

The FT8010 has two identical inputs for single or dual switch resetting capability. The device has two outputs: a push-pull output with 0.5mA drive and an open-drain output with 0.5mA pull-down drive.

The FT8010 draws minimal ICC current when inactive and functions over a wide power supply range of 2.0V to 5.0V.
