STM6601DA2BDM6F

STM6601DA2BDM6F is a smart push-button on/off controller with Smart Reset™ and power-on lockout. This device monitors the state of connected push-button(s) as well as sufficient supply voltage. An enabled output controls power for the application through the MOSFET transistor, DC-DC converter, regulator, etc. If the supply voltage is above a precise voltage threshold, the enabled output can be asserted by a simple press of the button. Factory-selectable supply voltage thresholds are determined by highly accurate and temperature-compensated references. An interrupt is asserted by pressing the push button during normal operation and can be used to request a system power-down. The interrupt is also asserted if undervoltage is detected. It is used in applications such as portable devices, terminals, audio and video players, cell phones and smartphones, PDAs, palmtops, and organizers.
