In a large bowl, whisk together the flour, sugar, baking powder, baking soda and salt.
Separate the egg yolks and egg whites into two bowls.
Add the ricotta cheese to the bowl with the egg yolks and whisk until combined, then whisk in the orange juice.
Using an electric mixer or whisk, beat the egg whites until stiff peaks form. Fold the egg whites and chocolate chips into the batter. (Do not overmix the batter. It should be lumpy.)
Preheat a griddle or grill pan over medium heat. Add 1/4-cup portions of the batter onto the griddle, spacing the pancakes at least 2 inches apart. Once bubbles form across the entire surface of each pancake, flip them once and continue cooking an additional 1 to 2 minutes.
Transfer the pancakes on plates then top with maple syrup and serve.
