BQ25672: Pre-production PQ25672 not 672 but 792?

Part Number: BQ25672

I ordered 10 samples of the PQ25672RQMT when they became available (pre production)  After placing on our board they seem to be providing the boost function and the actual parts are labeled as below:

TI
PQ2579x
HRS  A0
05A2CR8

Are these 25672 or are they 25792?  If the latter can the PL send me several 672 for evaluation since these were shipped incorrectly?  They are not available through distribution. We would like to get in line and place a volume order but would like to verify the 672 first.

Second question. What is the reverse mode mentioned as the difference in the 792 vs the 672?
