Abstract
This document discusses, among other things, an electronic circuit and method for defaulting to a valid battery supply to power an electronic device. In an example, an electronic circuit can be configured to receive information about the battery supply (e.g., an internal battery), such as the battery supply voltage (V), and to determine if the battery supply is valid or invalid using the received information (e.g., comparing the Vto a threshold). If Vis valid, the electronic device can default to receiving power from the battery supply. If Vis invalid, the electronic device can receive power from another power supply, such as an external supply.
