BQ2084+BQ29312 Sleep or Ship Mode

Other Parts Discussed in Thread: BQ29312

Hi Tiers.

We designed battery-pack using BQ2084+BQ29312.

When battery-pack is not used, battery-pack's capacity is slowly decreased.

So in this case, We want to set sleep mode or ship mode.

But We don't know how to set these modes.

How can I set below sleep or ship mode?

How can I set the register STATE CTL(b0) or (b1)?

    Have you tried the Sleep an Shutdown mode setups outlined on page 26 of the datasheet? I have not tried them on this device, but they are the same setups that I used on other devices. I do not think that you have access to the AFE State CTL register. Why do you want to change it?
