STM6601AU2DDM6F

STM6601AU2DDM6F is a smart push-button on/off controller with Smart Reset™ and power-on lockout device which is used to monitor the state of connected push-button(s) as well as sufficient supply voltage. If the supply voltage is above a precise voltage threshold, the enable output can be asserted by a simple press button. The 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 by a long push button (PB) or two buttons(PB and SR) either a reset is asserted or power for the application is disabled depending on the option used. They are ideal for portable devices, terminals, audio and video players, cell phones and smart phones, PDAs, palmtops, organizers.
