New Description: *:.> [New Technology Area] This notebook provides a choice of backup power supply unit for use in a handheld computer (Pocket pc) and θ power mode selection. Provide appropriate power office #, according to the supply device. ^ 7 Power supply for electric knife and port load [Prior Art] When the general handheld computer (PocketPC) is in low power supply (l〇w Battery), its power management usually adopts standard mode or high quality. Mode (Premium M〇de), which manages the power of the handheld computer. In the standard mode (Blessing (4) Shi (5), when the main battery of the Pocket PC is exhausted or removed, the status data generated by the handheld brain is automatically stored in the memory, and the backup battery provides power to the memory. The real time clock (Real Time c1〇ck^RTC) is at least 30 minutes to maintain the data and time. In addition, in the Premium Mode, the backup battery only provides power to the Real Time Clock (RTC) to keep The date and time of the handheld computer is about 168 hours. - The monthly reference to the first figure is a block diagram of the power supply device of the conventional handheld computer. The power supply device includes a main battery 14: a charging unit 19, a The backup battery 18 and a power output unit 16. In the case of normal power supply of the handheld computer, the main battery 14 supplies voltage to a real time clock 2 in the handheld computer and a memory unit 3, and also through the charging unit 19 The backup battery 18 is charged. The memory unit 3 is usually a synchronous dynamic random access memory (SDram>. M3 3 3 605 quasi-module-Γ power supply device 1 The architecture can only be used in the management mode of the Standard Mode. 1Fire knows, when it is removed or removed, the handheld computer will change the backup voltage from the backup battery 18 to the power output unit 16 , = Let the power output unit 16 generate the supply voltage to the real-time clock 2 and the record: 3 to: (10) and, the file data generated by the handheld computer will be self-blocking to the memory unit 3 'the backup battery 18 _ ::Γ=Integrity of the data. The foregoing rights and materials include edits: :枓, programs in use, and other settings. Same as _, the real-time clock 2 will also maintain the state of the handheld computer, time, etc. However, the backup battery 18 needs to be powered simultaneously to the real-time clock 2 disks, so the power can only be maintained for about 3 〇 minutes to 9 〇 minutes 2 and 'after the power is exhausted, it is stored in the memory unit 3 The file will disappear. 1 In summary, the traditional power supply i architecture can only provide power for handheld computers with low power supply in the standard mode (Standard Mode) management. Therefore, this architecture is limited by Standard Mode It is impossible to provide long-term power to maintain: the operation of unit 3 and real-time clock 2. The same day, it can not provide users with flexible selection of standard mode (Premium Mode) or high-quality mode (Premium Mode) power management means In view of this, this creation provides a selective backup power supply device that is used in a handheld PC (Pocket PC) and in the case of a low power supply (Low Battery) in the handheld computer. It provides the choice of two power management methods: standard M333605 f (Standard M〇de) or premium mode (Premium Mode). — * The selective backup (4) supply device of this creation is for the f-real-time % deduction and memory unit use, which includes a backup battery, a first electric, a single output, and a second power output unit. Among them, the backup battery is ready for power. The first power supply unit is coupled to the backup battery and receives the backup voltage and outputs a first supply voltage to the clock. The second power output unit is connected to the backup battery and the memory system to receive the backup voltage, and according to the -selection signal, outputting the output voltage to the memory unit or stopping outputting the second supply voltage 0 * according to the foregoing In the case that the handheld computer is in the low power supply C owBattery), the second signal can be output according to the selection signal, and the standard mode (refueling with μ_) is used as the source officer. The selection of the means, or the output of the second supply of electric dust is stopped according to the selection signal, and the quality mode (Premium Mode) is selected as the source management means. Horsepower [Embodiment] The second picture of the Ming Zheng test is a schematic diagram of the road block of the creative backup power supply device. The selective backup power supply device 4 is applicable to a handheld backup device (Pocket PC) t, which is connected to a real-time clock 2 and a record 3' and is capable of supplying power to the selective backup of the real M333605 by selecting the signal S1. The power supply device 4 mainly includes a backup power/output unit 42 and a second rear unit 44. The 'backup battery 46 is used to turn off a backup electric dolphins, and the second power supply output unit 42 is connected to the backup battery # and the real time day ^. The brother ί receives the backup voltage Vb, and the turn-out-supply voltage V1U % clock 2 is used. The second power supply and/or memory unit 3 receives the backup_outside, and the number = ' and the output - the second supply of the electric gate % to the memory unit = ^ the second supply voltage V2. A τ wheel and another brother a power supply unit 42 is 彳±t has a $2 production two ^ 44 also raises ^ ° the same 'second power output unit jt, with - over discharge protection function to prevent backup (four) Vb pairs i is over-discharged and is also available in the right zone 7 -
