HI team,
I see in our datasheet, BQ27426 could only get three pre-defined chemistry profiles, cannot be programmed with specific chem ID. However, in BQ studio, I could program BQ27426 with a chem ID, does this make sense? Could you give some comments to this?
Thanks and Best Regards,
Will
Hi Andy,
Could you help me understand why it's not recommend for ROM gauge? I see BQ27426 get a OTP option, could we use OPT to program the golden image file into it?
Regards,
Will
Hi Will,
As I mentioned above, this device is defined as a ROM gauge and there is basically no OPT option for the Chem ID.
The ChemID is only loaded into the data memory in RAM if you select a ChemID in bqSudio. Its contents are lost after a power cycle or reset.
