The want to add input anti-reverse protection function using TPS25947, which means the GND pin is +5V, and IN pin is 0V.
And in this situation, the circuit will not break down.
Is there any recommendation design using TPS25947 or other devices?
One solution I know is add a diode between board GND and device GND pin.
When the board GND is +5V, the diode will block the voltage and the device GND pin is still 0V.
But in the normal condition, there will be a 0.7V voltage lift in the device GND pin compared to the board GND.
Is there any other risk?
The second question:
What is the difference between TPS259470"A"RPWR and TPS259470"L"RPWR? The customer is asking this quesiotn.
