ELECTRONIC DEVICE
First Claim
1. An electronic device, comprising:
- a battery module;
a first switch circuit, coupled to the battery module;
a connector, coupled to the first switch circuit;
a voltage stabilizer, coupled to the connector; and
a controller circuit, coupled to the voltage stabilizer, the connector, the first switch circuit and the battery module, and a configuration channel being implemented between the controller circuit and the connector;
wherein when a voltage of the battery module is lower than a threshold voltage and the connector is only connected to a first power source, the first power source provides an activating voltage to the controller circuit through the voltage stabilizer, so as to enable the controller circuit, the connector sends a first detection signal to the controller circuit through the configuration channel, and the controller circuit sends a first control signal to turn on the first switch circuit according to the first detection signal, so that the first power source charges the battery module through the first switch circuit.

Abstract
An electronic device includes a battery module, a first switch circuit, a connector, a voltage stabilizer and a controller circuit. The controller circuit is coupled to the connector and the first switch circuit. A configuration channel is implemented between the controller circuit and the connector. When a voltage of the battery module is lower than a threshold voltage and is only connected to a first power source, the first power source provides an activating voltage to the controller circuit through the voltage stabilizer, so as to enable the controller circuit. The connector sends a first detection signal to the controller circuit through the configuration channel. The controller circuit sends a first control signal to turn on the first switch circuit according to the first detection signal, so that the first power source charges the battery module through the first switch circuit.
