BQ4050: BQ4050-EVM Wake Button

az ert

Part Number: BQ4050

Hi all,

If the battery pack was unplugged from bq4050-evm.

Is it necessary to press the "Wake" push-button after re-plugging the battery pack ?

Thank you.

If you don't have a pack side connection, the wake button enables the gauge to wake up by shorting pack and bat terminals.

Thank you for your reply,

But what do you mean by "If you don't have a pack side connection" ?

The battery pack was unplugged.

By that I mean if the charger was disconnected or the battery was unplugged.

The pack side terminals connect to the charger. In our naming we use BAT as the connection to the battery pack and PACK as the connection to charger.

Thank you Batt,

So:

Suppose that the charger is always disconnected (there is no pack side connection).

Is it necessary to push the button "Wake" every time I plug the same battery ?

Yes, on the evm that is how it's designed.
