Animals hibernate for many different reasons, but it all comes down to conserving energy. Unlike bears, small mammals like chipmunks lose heat quite easily, forcing them to wake up every few days to warm up, urinate, and eat.

By going into a long deep sleep, they bypass this period completely, waking.
