Abstract
An electronic device having an auto-on circuit is provided. The electronic device can include a charging circuit and a control circuit. The control circuit can cause the charging circuit to deliver energy to an external device. The auto-on circuit, which can include an active circuit, can activate the control circuit in response to one or more trigger input circuits. Each trigger input circuit can actuate a switch and deliver an auto-on signal to the control circuit. The control circuit can then actuate a latch to deliver power to a power input terminal to keep itself powered ON.
