ST’s smart reset ICs extend the functional capacity of existing buttons so that users can reset their frozen device with a long push of one or two buttons simultaneously. These devices integrate several useful features, such as:
- No need for a specific reset button – an existing button or combination of buttons can be used
- Customizable input delay time from 5 to 10 second, that ensures that inadvertent, short activation of the button(s) do not cause a system reset
- Choice of a single button or two simultaneous buttons to signal a reset
- Support for applications where the battery is unremovable
- Very small packages (DFN and UDFN) for minimal impact on board size
