BQ27220: Flags()[ITPOR] missing

Gary Jiang

Part Number: BQ27220

Hi team,

My customer now uses BQ27220 and they want to use Flags()[ITPOR] bit to flag if RAM configuration is reset to default configuration. But we can't find the address of this bit in Batterystatus(). So please help me find out where and how to read this bit? Thank you!

As far as I know, that bit doesn't exist.

See the following thread.

Hi Andy,

If so, my customer now wants to know when the RAM is reset to default configuration as soon as possible(ITPOR function). Can you recommend some good solution on BQ27220?

Many thanks!

Hi Gary,

I have not seen a bit that can serve that purpose yet. How does the customer program their configurations to the gauge device?
