ADIS16265 - Reverse current protection

I was testing ADIS16265 breakout board, and accidentally had the VCC and GND connection the other way around.

For quick moment there was 2A shown from the power supply, but this was quickly disconnected.

After the VCC and GND connection had been fixed, the power supply was showing the expected current drawn by the gyro (0.04A) and the gyro seemed to behave just as normal (output rate and temperature reading seemed alright, the output rate corresponds to the manual rotation tested on the gyro).

My question is, is there reverse current protection circuit inside the gyro chip?

If yes, that would be a great relief.

If not, what is the risk of impairing the chip? Is there internal damage to the chip that is not visible to user?

Will there be reliability problem to the chip?

Looking forward to clarifications. Thank you in advance.
