Further, between described the first stand-by power supply and described the first power-supply controller of electric, be electrically connected to one first power supply protector, between described the second stand-by power supply and described second source controller, be electrically connected to a second source protector.
Further; described main power source is DC power supply; described the first stand-by power supply, the second stand-by power supply are button cell; described main power source controller, the first power-supply controller of electric, second source controller are diode, and described the first power supply protector, second source protector are current-limiting resistance.
The utility model has the following advantages with respect to prior art after adopting technique scheme:
The double spare power circuit design of the utility model data storage device, by two stand-by power supplies in parallel and power-supply controller of electric thereof, be electrically connected in VBAT node power supply data storage device, when main power source power down, even the first stand-by power supply power down, the second stand-by power supply also can continue as data storage device power supply, to guarantee that data storage device still can work, thereby avoids the loss of data of data storage device stores.
The double spare power circuit of this data storage device is simple and reliable, efficiency is high, cost is low, has applicability widely, is applicable to allly need to utilize the equipment of stand-by power supply save data or the stand-by power supply circuit of other electronic products.
Accompanying drawing explanation:
Fig. 1 is circuit diagram of the present utility model.
Embodiment:
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only instrument in order to explain the utility model, and be not used in restriction the utility model.
Referring to Fig. 1, the double spare power circuit of a kind of data storage device providing according to the utility model, comprise main power source 1, the first stand-by power supply 2, the second stand-by power supply 3, for controlling the main power source controller 11 of main power source 1, for controlling the first power-supply controller of electric 21 of the first stand-by power supply 2 and for controlling the second source controller 31 of the second stand-by power supply 3, the first stand-by power supply 2 and the second stand-by power supply 3 parallel joins, its two power cathodes ground connection, described main power source controller 11, the first power-supply controller of electric 21, second source controller 31 is parallel to a VBAT node 4, described VBAT node 4 is electrically connected to a data storage device 5.This circuit, by power controller controls You Na road Power supply, for guaranteeing the stable of VBAT node voltage, thereby improves the reliability of data storage device.
Between described the first stand-by power supply 2 and the first power-supply controller of electric 21, be electrically connected to one first power supply protector 22; between the second stand-by power supply 3 and second source controller 31, be electrically connected to a second source protector 32; the first power supply protector 22, second source protector 32 are current-limiting resistance; its resistance can be by a little Europe to several megaohms not etc.; for security consideration; prevent in the situation of diode fails, protection button cell is not by large current charge.
