DC1836A-A

DC1836A-A demonstration board for the evaluation of LTC2955IDDB-1 pushbutton On/Off controller with automatic turn-on. The LTC2955 is a micropower, pushbutton on/off controller that manages system power by generating a clean enable output from the supply monitor input and the debounced pushbutton input. It features an interrupt output that notifies the system of a pushbutton or low supply event. When the system is ready, it may use the power kill input to shut off power. If the pushbutton remains pressed for more than the configurable turn off duration, the system power is forced off. The robust pushbutton input handles wide voltage swings of up to ±36V and ESD strikes up to ±25KV, and is designed to operate in noisy environments. A mode select pin enables users to select automatic turn on and turn off combinations, and battery run time is maximized.
