<![CDATA[Power dock shuts down when no battery connected]]>Re: Power dock turning off after 30 minutes

I can verify that my power dock has the problem reported in the referenced thread. With no battery attached, the dock shuts down after less than an hour. By "shuts down" I mean that the LEDs on the dock go dark and no power gets to the Omega. I need to remove the power connection and reconnect to get the dock and the Omega working again.

However, if I plug a battery into the dock, the dock power LED lights, and power is BRIEFLY restored to the Omega. Then the Omega LED goes dark. If I plug in a battery BEFORE I apply power to the miniUSB port, then the dock behaves normally.

"Backup Battery Pack Manager" per its datasheet.

It should provide some clue about operating such design without battery always connected to the circuit in the first place.

-Backup Battery Pack
-Power Bank
-Mobile Power
-Standalone Battery Charger with USB Output

I didn't see any statement that the circuit "requires" a battery to be connected. I might have missed it.

Is this your IC design perchance? Thank you for pointing out the obvious, but the alternative applications bear some consideration. As a user of the board, I am just trying to get some clarification as to the proper use. If I need to attach a battery for proper operation, then so be it. But please do not simply circle a part of the datasheet without comment.

Have issues, talk to Onion directly.
