Many battery powered devices do not allow them to be operated while the battery is being charged. I know how to do that with a switched charging jack like this:
1) Is there a more common, sophisticated, expensive, or solid-state way to do that?
2) I am going to be using an On/Off controller (e.g., MAX16054) and a boost converter (NCP1402 at 5V). The battery pack will consist of three, AAA NiMH cells in series. Is it really necessary to have a disconnect during charging? Assuming the charge voltage doesn't exceed 5V, how would turning the system on, say accidentally, during charging be a problem?
Thanks, John
