Power Good
The SQ2131 includes the Power Good feature.When the output is not within 15% of the specified voltage, it pulls low. This can occur
under the following conditions: 1. Input Votage Too Low. 2. During Over-Temperature. 3. During Over-Current. 1. If Output Is Pulled Up.
(Note: PG pin is an open-drain output.)
