BQ34Z100-G1: What does the datasheet mean by "Standard Configuration Options?"

Carolus Andrews

Part Number: BQ34Z100-G1

Team,

I have a customer that wishes to know the following:

What do we mean in the datasheet when we say 'standard configuration options?' Is this meant as without any scaling, i.e., default register settings? Could you please elaborate on what standard/non-standard means here.

hi Carolus
Standard in that case is referring to without scaling. if the customer wishes to use >29Ahr cell, they wil have to scale and we have app notes that describes this process.

thanks
Onyx

Dear Onyx,

Sorry for the second question: If the maximum capacity of the device is 29Ah, why do we stipulate on page 25 of the data sheet in the Data Flash Summary Section 32767 mAh as the Max value for Design Capacity? The same is true for QMax Cell 0 on page 28. Can you explain the discrepancy?

Hi Carolus,

Great question!

32767 is the largest value you can store in a 2 BYTE signed integer. The bits are already allocated and this allows for headroom for Qmax and Design Capacity.
