BQ2980: wake it up after inserting battery without signal on PACK+

eyall abir

Part Number: BQ2980

Hello,

I didn't get clear from previous collegue question.

I would like to understand clearly :

1. Do the BQ298xyz can only wake up with PACK+ from charger ? if does why it is the case? i dont understand the logic behind this. for example smarthpones are ON even before plug it to a charger.

2. Is there any way to wake it up after inserting battery without signal on PACK+ ? please suggest how.

Thank you
