Pushbutton Controllers

Analog Devices pushbutton controllers easily solve the inherent bounce problem associated with all mechanical contacts while enabling power supply converters and releasing a processor once the supply is fully powered up. Wide voltage operation, rugged ESD protection, small size, low quiescent current, and ease of design distinguish these pushbutton controllers from discrete implementations. All ADI pushbutton controllers feature a force shutdown fail-safe feature in case the microprocessor fails to respond to a pushbutton controller’s request to shut down.
