BQ25611D: Oddity/Question

Part Number: BQ25611D

Hello Team,

I have a question regarding BQ25611D. Data Sheet is SLUSDF8B revised 9/2020.

9.5.12 Part Information Register (Address = 0Bh)

Describes bits 3-6 as the PN and should report ‘1010’ (representing BQ25611D)

I can read all the register just fine. I’ve dumped them, tweaked writeable bits, verified.

When I read register 0x0B, I always get back 0x04, which means the PN is ‘0000’. Doesn’t matter if single register read or the whole block (as shown below).

What did I miss?

Thanks! 

Connor
