Technical field
The utility model belongs to circuit structure technical field, particularly relates to the circuit structure that a kind of power management IC realizes telepilot switching on and shutting down.
Background technology
Power management chip (PowerManagementIntegratedCircuits) is the chip of responsibility shouldering conversion to electric energy, distribution, detection and other electric energy managements in electronic apparatus system.But current power management chip cannot realize remote control switch, namely cannot realize being communicated with between power management chip and receiver of remote-control sytem.
In view of this, the necessary circuit structure providing a kind of power management IC to realize telepilot switching on and shutting down, it has assisted the work of remote control switch by a plug-in MCU.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provides a kind of power management IC to realize the circuit structure of telepilot switching on and shutting down, and it has assisted the work of remote control switch by a plug-in MCU.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of power management IC realizes the circuit structure of telepilot switching on and shutting down, comprise MCU, power management IC and receiver of remote-control sytem, first pin of described MCU connects external power supply, second pin of described MCU is connected with described power management IC, and described MCU exports the Push And Release that low and high level controls described power management IC, 7th pin of described MCU is connected with described receiver of remote-control sytem, and signal is inputted the 7th pin of described MCU by described receiver of remote-control sytem, the 8th pin ground connection of described MCU.
The one realizing the circuit structure of telepilot switching on and shutting down as the utility model power management IC is improved, and the 3rd pin of described MCU is empty pin to the 6th pin.
The one realizing the circuit structure of telepilot switching on and shutting down as the utility model power management IC is improved, and the model of described power management IC is JH8100.
The one realizing the circuit structure of telepilot switching on and shutting down as the utility model power management IC is improved, and the model of described MCU is B513.
Relative to prior art, the utility model has assisted the work of remote control switch by a plug-in MCU.Specifically, signal is inputted the 7th pin of MCU by receiver of remote-control sytem, and second pin of MCU then exports a low and high level to control the Push And Release of power management IC, thus achieves the object of the Push And Release controlling power management IC with telepilot.The utility model structure is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model.
Wherein:
1-MCU, 2-power management IC, 3-receiver of remote-control sytem.
Embodiment
As shown in Figure 1, a kind of power management IC that the utility model provides realizes the circuit structure of telepilot switching on and shutting down, comprise MCU1, power management IC 2 and receiver of remote-control sytem 3, first pin (vdd terminal mouth) of MCU1 connects external power supply (MCU_VDD), second pin (IOB5 port) of MCU1 is connected with power management IC 2, and MCU1 exports the Push And Release that low and high level controls power management IC 2,7th pin (IOB0 port) of MCU1 is connected with receiver of remote-control sytem 3, signal is inputted the 7th pin of MCU1 by receiver of remote-control sytem 3, the 8th pin ground connection of MCU1.
Wherein, the 3rd pin of MCU1 is empty pin to the 6th pin (respectively corresponding IOB4 port, IOB3 port, IOB2 port and IOB1 port), and reserved empty pin can make MCU connect other components and parts and chips etc., to expand its function.
The model of power management IC 2 is JH8100.Model is that the power management IC 2 of JH8100 adopts paster biserial 18 pin to encapsulate; it has following features: one is have over-voltage protecting function; during charging, voltage is more than 15V meeting auto-breaking; two is have Charge Management function; there is the function such as overcurrent protection, constant current protection; three is band screen backlight boosting 3V functions, and four is have low-voltage prompting function.
The model of MCU1 is B513, the MCU1 of this model not only can receive the signal input of receiver of remote-control sytem 3, and a low and high level can be exported to control the startup and shutdown that model is the power management IC 2 of JH8100, thus realize remote-controlled start-up and the remote-control closedown of power management IC 2.
In a word, the utility model has assisted the work of remote control switch by a plug-in MCU1.Specifically, signal is inputted the 7th pin of MCU1 by receiver of remote-control sytem 3, and second pin of MCU1 then exports a low and high level to control the Push And Release of power management IC 2, thus achieves the object of the Push And Release controlling power management IC 2 with telepilot.The utility model structure is simple, and cost is low, is easy to realize.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
