Terminal device
View Patent ↗A technology for charging the battery of a terminal device with efficiency. In a wireless game controller, a charge control unit supplies electric power from an external power supply to a battery. A communication management unit receives a drive request signal to a vibrating motor. A motor control unit supplies a drive current to the vibrating motor in accordance with the drive request signal. The charge control unit performs charge control for the battery in a first mode when the communication management unit does not receive the drive request signal, and performs charge control for the battery in a second mode when the communication management unit does receive the drive request signal. The charge control unit performs the charge control for the battery in the first mode using a charging current higher than that in the second mode.
1. A terminal device comprising:
a battery which stores electric power;
a charge control unit which supplies electric power from an external power supply to the battery;
a load which is driven by a drive current supplied thereto;
a communication management unit which receives a drive request signal for the load; and
a load control unit which supplies the drive current to the load in accordance with the drive request signal, wherein
the charge control unit performs charge control for the battery in a first mode when the communication management unit does not receive the drive request signal, and performs charge control for the battery in a second mode when the communication management unit does receive the drive request signal.
2. The terminal device according to claim 1 , wherein the charge control unit performs the charge control for the battery in the first mode using a charging current higher than that in the second mode.
3. The terminal device according to claim 1 , wherein the load control unit supplies the drive current to the load after a predetermined first time interval elapses since the communication management unit received the drive request signal.
4. The terminal device according to claim 1 , wherein when the communication management unit does not receive the drive request signal for a predetermined second time interval in the second mode, the charge control unit switches the charge control to the first mode.
