Hi team.

I'd like to know about RESET wait time.

How long should I wait for a command after RESET?

Sincerely.

I don't quite understand your question. Could you explain your question in more detail?

Hi Andy.

My customer want to use RESET commands when the battery is inserted.

I think RESET commands take time to process.

How long should we wait after RESET commands?

Sincerely.

Kengo.

Hello Kengo,

You can refer to the DS: http://www.ti.com/lit/ds/symlink/bq27510-g3.pdf

There's a page on I2C waiting times.

Hi Kang.

Is this a valid wait time after RESET command?

Sincerely.

Hello Kengo-san,

A reset command should be the same as a power on reset. I would wait that long until you need to read the registers from the gauge.

Hi Kang-san.

What I want to ask is how many seconds need to wait.

Could you tell me more detail?

Sincerely.

Hello Kengo-san,

This one is tough to know. Very hard to characterize. I would recommend trying this on a lab setup and adding some guard band once you have some typical numbers. We just don't have a spec for this.
