Overview
The STM6600AS24DM6F is a smart push-button on/off controller developed by STMicroelectronics. This device is designed to monitor the state of connected push-button(s) and ensure sufficient supply voltage. It features Smart Reset™ and power-on lockout capabilities, making it ideal for managing power in various portable and consumer electronic devices. The controller allows the enable output to be asserted by a simple press of the button if the supply voltage exceeds a precise, factory-selectable threshold. It also includes interrupt functionality for system power-down requests and undervoltage detection.
