TPS62125: How to use Power Good (PG) to implement Low Battery indicator

Part Number: TPS62125
Other Parts Discussed in Thread: TPS3710


I have TPS62125 sourced with a 16.5V battery. Its Vout is set to 3.3V to power an MSP430 MCU.

MSP430 is used, among others, to monitor low battery, e.g. when battery voltage <14.5V, through PG pin.

- Is this possible? (i.e. PG becomes low when input voltage < V_threshold, while TPS62125 still powers MSP430)

- Is there a simple circuit to be implemented?

Many thanks.

Best regards,
