That chip seems like overkill for what I need. Also, the buck/boost converter does more than I need as well. I don't need a low battery voltage to be boosted to power the Arduino. Instead, I just want the power to be prevented from reaching the Arduino if the voltage is too low and could therefore damage the Arduino with a voltage outside of its operating range. Does the on-board voltage regulator do this automatically? As in, if the supplied voltage to the RAW pin is too low, will it recognize this and not try to power itself?
