What concern do you have if we use bq27520-G4 with "Update Status" is 00?

Can we use bq27520-G4 with this configuration? Is the concern only influence for gauge accuracy?

Or update status must be 02?

Hi Kohei

an update status that is not 2 means learning never successfully completed. you can expect to have accuracy issues if update status doensn;t get set to 02 by the gauge. It has to be 02

thanks

Onyx-san,

Is there any problem about device function or operation? Is not the electrical characteristics guaranteed if we use the device like that?

Hi Kohei,

Eectrical characteristics will be ok. What will not be ok is the gauging accuracy.

thanks

Thank you for your reply.
I think we can use the device that update status is not 02 if customer allows gauging accuracy although I understand you cannot recommend.

Do you have any concern other than gauging accuracy?
