ANALOG DEVICES DC2254A-B

DC2254A-B demonstration circuit features the LTC2956-2. The LTC®2956-2 is a micropower, wide input voltage range, configurable wake-up timer with pushbutton control. It periodically wakes up and turns on a connected system to perform tasks like monitoring temperature or capturing images. After completing the task, the LTC2956-2 turns the system off to conserve power. The wake-up timer period can be adjusted from 250ms to 39 days. Onboard jumpers, and an 8-pin DIP switch provide a range of value options, to set the wake-up timer, wake-up timer period and long power down time. Turrets are also present, allowing direct access to all the pins present on the LTC2956-2 to allow easy interfacing with a system with arbitrary requirements.
