高电压按钮控制器

The LTC®2954 pushbutton on/off controller with µP interrupt manages system power via a pushbutton interface. An enable output toggles system power and an interrupt output provides debounced pushbutton status. The interrupt output can be used in menu-driven applications to request a system power down. A power kill input allows a microprocessor or system to reset the enable output, effectively powering down the system. Adjustable on and off timers provide dependable pushbutton control of the enable output and resistance to accidental toggling of system power.
