SR2 6-Pin Smart Reset™ Switch

STMicroelectronics SR2 6-Pin Smart Reset™ Switch is designed to ensure that inadvertent short reset push-button closures do not cause system resets. This is done by implementing extended Smart Reset input delay time (t_SRC) and combined push-button inputs, which together ensures a safe reset and eliminates the need for a specific dedicated reset button. This reset configuration provides versatility and allows the application to distinguish between a software generated interrupt and a hard system reset. When the input push-button are connected to microcontroller interrupt inputs, and are closed for a short time, the processor can only be interrupted. If the system still does not respond properly, continuing to keep the push-button closed for the extended setup time t_SRC causes a hard reset of the processor through the reset output.
