The control subelement 304 is to drive the touch-control pens unit 20 and the control subelement 304.
If the control subelement 304 judges the cell voltage of the battery subelement 302 no more than the electricity
Pond predeterminated voltage, then the control subelement 304 is not turned on the cell switch subelement 308, so that the charge and discharge electronics list
First 306 electric discharges/power supply (wherein, the voltage of the charge and discharge electronic unit 306 can be discharged to 0 volt from such as 2.7 volts) is to institute
Third charging subelement 318 is stated, then the touch-control pens unit 20 and the control are supplied power to by third charging subelement 318
Subelement 304 is to drive the touch-control pens unit 20 and the control subelement 304.
The boost voltage detecting subelement 322 is to detect the voltage of the charge and discharge electronic unit 306 and notify
The voltage of charge and discharge electronic unit 306 described in the control subelement 304；When the power supply device 40 stopping supplies power to
The stylus power-supply unit 30 and the control subelement 304 judge the battery electricity of the battery subelement 302
Pressure is no more than the battery predeterminated voltage and boost voltage detecting subelement 322 detects the charge and discharge electronic unit 306
The voltage be greater than predetermined voltage (for example, 1.4 volts) when, the control subelement 304 by the voltage control son singly
324 control of the member third charging subelement 318 provides the first output voltage (for example, 2.8 volts) to the touch-control pens unit
20 and the control subelement 304；When the power supply device 40 stopping supplies power to the stylus power-supply unit 30
And the control subelement 304 judges the cell voltage of the battery subelement 302 no more than the battery predeterminated voltage
And the voltage that the boost voltage detecting subelement 322 detects the charge and discharge electronic unit 306 is not more than described make a reservation for
When voltage, the control subelement 304 controls the third charging subelement 318 by voltage control subelement 324 and mentions
For the second output voltage (for example, 2.2 volts) to the touch-control pens unit 20 and the control subelement 304；Described first is defeated
Voltage is greater than second output voltage out；Whereby, the power-on time of the charge and discharge electronic unit 306 can be extended.
The first charging subelement 314 is decompression charge integrated circuit, such as receive 5 volts of voltages are reduced to
4.2 volts of voltage outputs；The second charging subelement 316 is decompression charge integrated circuit, such as by receive 4.2 volts
Voltage is reduced to 2.7 volts of voltage outputs；The third charging subelement 318 is boost charge integrated circuit, such as will be received
2.7~1.5 volts of voltages be upgraded to 2.8 volts of voltage outputs, or the voltage less than 1.5 volts received is upgraded to 2.2 volts
Special voltage output.If the cell voltage of the battery subelement 302 is no more than the battery predeterminated voltage but also still
If continued power use, then it is easy to damage the battery subelement 302, therefore the utility model is set as the electricity
The cell voltage of pond unit 302 stops being powered by the battery subelement 302 no more than the battery predeterminated voltage.
Referring to FIG. 2, the configuration schematic diagram of its touch-control pen device for the utility model with dual power supply source.The tool
There is the touch-control pen device 10 in dual power supply source also comprising stylus shell 102 and circuit board 104；The stylus shell 102 wraps
