The details of the terminal device of present embodiment is specifically described below, the following contents only mentions for convenience of understanding
The details of confession not implements the necessary of this programme.
It specifically, is a kind of a kind of specific connection schematic diagram of charging modes in the prior art referring to Fig. 1, Fig. 1.?
It is carried out in charging process by the charging modes, be divided into charging and two kinds of situations of non-charging: charging module 15 and charging equipment connect
It connects, when charging equipment is in charged state, charging module 15 is supplied by inductance 17 directly to power management module 12 or load
Electricity.When charging equipment is in non-charged state, battery module 11 gives power management by the metal-oxide-semiconductor 16 inside charging module 15
Module 12 or load supplying.It will be understood by those skilled in the art that due in the charging modes of belt path management, battery module
There is a metal-oxide-semiconductor 16 between 11 and power management module 12, and there are impedances for metal-oxide-semiconductor 16, although impedance very little, in power consumption
When electric current when component operation is larger, the voltage of power management module 12, the especially electricity in battery module 11 can be dragged down moment
When measuring lower, when power consumption components 14 (power consumption components 14A, 14B in Fig. 1 are only to indicate multiple and different power consumption components) work
The larger situation of electric current is easy to be triggered to the under-voltage locking of power management, causes that system is powered down.In figure for convenience of explanation only
Two power consumption components (power consumption components 1 and power consumption components 2) are shown, but are not limited to this in practical application.Wherein, under-voltage locking
Mode is as one when opening threshold voltage of the supply voltage lower than integrated circuit (Integrated Circuit, referred to as " IC ")
Kind protected mode, undervoltage turnoff mode can guarantee that IC is unlikely to be damaged in supply voltage deficiency.
Such as due to having a metal-oxide-semiconductor 16, the impedance of metal-oxide-semiconductor 16 between battery module 11 and power management module 12
At least 10 milliohms, moment power consumption when wherein power consumption components are started to work is maximum, if it is 5A, metal-oxide-semiconductor 16 that moment, which takes out load electric current,
Impedance when conducting is 0.03 Ω, then battery module 11 can reduce 5A*0.03 Ω to the voltage between power management module 12
The voltage that=0.15V, i.e. moment can be pulled down to power management module 12 is 0.15V, larger especially when battery capacity is lower

It causes that system is powered down, influences the usage experience of user.
Referring to fig. 2, Fig. 2 is the structure connection diagram of the terminal device in present embodiment, the end in present embodiment
End equipment includes: power consumption components 14, battery module 11, power management module 12 and DC-DC module 13.Battery module 11 is distinguished
It is connect with power management module 12 and DC-DC module 13.
It is present embodiment referring to Fig. 3, Fig. 3 in order to which the vivider terminal device in present embodiment is illustrated
A kind of specific connection schematic diagram of middle terminal device.Terminal device in Fig. 3, including charging module 15；Charging module 15 divides
It is not connect with power management module 12 and battery module 11；Charging module 15 is used for external charge equipment, at charging equipment
It is that power management module 12 and battery module 11 are powered when charged state；Wherein, battery module 11 and power management module
There are a metal-oxide-semiconductor 16 and inductance 17 between 12, metal-oxide-semiconductor 16 is for controlling leading between battery module 11 and power management module 12
Logical and shutdown, inductance 17 is the component in charging circuit, is used for energy storage and electric discharge.Battery module 11, specifically for charging
It is the power supply of power management module 12 by the metal-oxide-semiconductor 16 in charging module 15 when module 15 is in non-charged state.
Specifically, power management module 12 are also used to read the electricity of battery module 11 in addition to powering to power consumption components 14
Amount turns off default branch if electricity is lower than default electricity.DC-DC module 13, for default in the shutdown of power management module 12
While branch, the default branch that management module 12 is turned off is powered on, power for power consumption components 14.That is, in electricity
When module 11 electricity in pond is low, power management module 12 turns off default branch (current path for ending the default branch), together

Part 14A and power consumption components 14B is only to indicate multiple and different power consumption components, in practical applications should not be as limit.
Wherein, default electricity mentioned here can be set according to specific power consumption situation and user experience, such as can be with
Setting are as follows: the 15% to 30% of 11 total electricity of battery module.That is, if default electricity is 11 total electricity of battery module
30%, then power management module 12 turns off the branch 1 in Fig. 3, while starting DC-DC mould when battery capacity is 30%
Block 13 is powered to power consumption components 14.In addition, DC-DC module 13 mentioned here can be understood as conversion module or circuit, this
Embodiment is not especially limited.

On can be regarded as high current, such as the size of current consumed when flash lamp operation be 1.5A, graphics processor (Graphics
Processing Unit, referred to as " GPU ") work when the electric current that consumes can achieve 2A to 3A even more than, the steering engine of robot
It is possible that higher, peak value is possible to reach 7A.Described predetermined current threshold can be set to 1A in present embodiment.
It should be noted that the electric current consumed in default branch concrete foundation power consumption components 14 work manually set is big
It is small set in (power consumption according to power consumption components 14 can also be expressed as to be set, because the bigger power consumption of electric current is more
Greatly), power consumption mentioned here can be average power consumption.In practical applications, it is also necessary to consider wink when power consumption components 14 start
When current value, wherein instantaneous current value when power consumption components 14 start is commonly greater than 1.5 times or more of current average, starting
When instantaneous current value be also to be easy to be triggered to one of key factor of UVLO.For example, the average current value of a branch is
3A, instantaneous current value when power consumption components 14 start are likely to be breached 4.5A, if impedance when metal-oxide-semiconductor is connected is 0.03 Ω, that
, only this branch may drag down the voltage of battery module 11 moment are as follows: 4.5A*0.03 Ω=0.135V, battery module 11
When electricity is lower than default electricity, voltage 0.135V or more is dragged down suddenly, is just easy to be triggered to UVLO.
In addition, it should also be noted that, the DC-DC module 13 in Fig. 3 is two (respectively DC-DC module 13A and DC-
DC module 13B) by way of example only, it in practical applications should not be as limit.The quantity of DC-DC module 13 can be according to reality
The factors such as the size of current of situation such as branch, the amount of capacity of battery module 11 and the usage experience that whether influences user
It is set, under the premise of the voltage of each branch requires all the same, it is multiple that a DC-DC module 13, which can also only be arranged,
Road power supply.When mobile terminal is mobile phone, the voltage of each branch requires generally difference, therefore can be according to specific design requirement
Multiple DC-DC modules 13 are set, and a DC-DC module 13 is not the DC-DC mould of setting to a branch power supply
Block 13 is The more the better, this is because the DC-DC module more than 13 of setting, cost is higher.
