A major feature of the LTC2956 is its code-free adjustability. All adjustable timing parameters on the LTC2956 are set using external resistors or capacitors. Resistors tied to the PERIOD and RANGE pins allow users to set the wake-up timer period anywhere from 250ms to 39 days; in the context of photography, an intervalometer could be set to take a rapid succession of shots 250ms apart, or take one shot every 39 days. Resistors tied to the LONG pin allow users to set how long an optional pushbutton must be pressed in order to shut down the wake-up timer; this feature is good for applications where the system may need to be occasionally powered up or down on command. The same LONG pin is also used to select how the LTC2956 behaves upon power up, with the wake-up timer running or stopped. Additionally, a capacitor on the ONMAX pin limits the amount of time a system can be on, acting as a failsafe measure by preventing any system from erroneously staying on forever.
