Overview
The STM6503VEAADG6F is a dual push-button smart reset IC produced by STMicroelectronics. This component is designed to provide a reliable and adjustable reset mechanism for various electronic systems. It features two combined Smart Reset inputs (SR0 and SR1) with user-selectable setup delays, ensuring that inadvertent short reset push-button closures do not cause system resets.
