Abstract
An electronic apparatus including an RT/CMOS DATA logic unit which stores Real-Time Clock information and CMOS information, and a battery having a power terminal to supply main power used in the electronic apparatus and a signal terminal for data communication with the electronic apparatus, and when the main power is turned off, supplies power to the RT/CMOS DATA logic unit through the signal terminal to maintain operations of the RT/CMOS DATA logic unit.
Claims20
An electronic apparatus comprising:
- an RT/CMOS DATA logic unit to store Real-Time Clock information and CMOS information;
- and
- a battery including a power terminal to supply main power used in the electronic apparatus and a signal terminal for data communication with the electronic apparatus, and, when the main power is turned off, the battery supplies power to the RT/CMOS DATA logic unit through the signal terminal to maintain operations of the RT/CMOS DATA logic unit.
A battery used in an electronic apparatus, the battery comprising:
- at least one battery cell;
- a power terminal to supply main power to the electronic apparatus;
- a signal terminal to perform data communication between the battery and the electronic apparatus or to supply power to an RT/CMOS DATA logic unit which stores Real-Time Clock information and CMOS information;
- a pull up resistance to provide power supplied from the at least one battery cell to the signal terminal;
- and
- a battery manager to supply power to the RT/CMOS DATA logic unit through the signal terminal when the main power is turned off, and to perform data communication between the battery and the electronic apparatus through the signal terminal when the main power is turned on.
A battery usable in an electronic apparatus, the battery comprising:
- at least one battery cell;
- a first power terminal to supply main power to the electronic apparatus;
- and
- a second power terminal to supply power to an RT/CMOS DATA logic unit which stores Real-Time Clock information and CMOS information,
- wherein the second terminal is a terminal which supplies power to the RT/CMOS DATA logic unit to maintain operations of the RT/CMOS DATA logic unit regardless of on/off state of the main power.
A power supply apparatus to supply power to an RT/CMOS DATA logic unit which stores Real-Time Clock information and CMOS information, the power supply apparatus comprising:
- a battery to store power;
- and
- a power supply controller to control power supply to the RT/CMOS DATA logic unit, using power supplied from the battery,
- wherein the battery comprises:
- a signal terminal to perform data communication between the battery and the electronic apparatus or to supply power to the RT/CMOS DATA logic unit;
- and
- a power terminal to supply main power to the electronic apparatus, and the power supply controller enables power supplied from the power terminal or the signal terminal to be provided to the RT/CMOS DATA logic unit, according to on/off state of the main power.
An electronic apparatus, comprising:
- a battery having a power terminal to output a main power, and a signal terminal to selectively output data and a sub-power.
