BQ25601D: Incorrect Device Part Number over I2C

Part Number: BQ25601D

Hello,

We are working with BQ25601D and are observing an unexpected result when reading back the device ID. In register 0x0B bits 3-6 are expected as 0111 corresponding to this device. Over I2C we read register 0x0B as 0x11. Bits 3-6 are 0100. The package marking is BQ 25601D TI 9A8 A9F7. Should this be a cause of concern or is there anything else that can cause the reprogramming of these bits or benign manufacturing programming error? 


Regards,


Garret
