As shown in figure 4, first embodiment of the invention proposes a kind of OTG equipment, including：OTG device 401 and charging unit
402, wherein
The USB charging voltage port VBUS of OTG device 401 is electrically connected with the USB charging voltage port VBUS of charging unit 402
It connects, the grounding ports GND of OTG device 401 is electrically connected with the grounding ports GND of charging unit 402, the detection of charging unit 402
Positive port D+ and detection negative terminal mouth D- are shorted.
Power management chip PMIC when the OTG equipment of the embodiment of the present invention is accessed mobile terminal, in mobile terminal
Be still OTG device 401 in OTG equipment rather than charging unit 402 identifying, and the principle of existing charging unit be by
USB charging voltage port VBUS, grounding ports GND, the positive port D+ of detection and detection negative terminal mouth D- and power management chip PMIC
After being connected, by power management chip PMIC according to the input-signal judging charging dress for detecting positive port D+ and detection negative terminal mouth D-
Setting is standard charger also criteria of right and wrong charger, carries out controlling its charging voltage and current accordingly and entering charging mould
Formula.Therefore in embodiments of the present invention, by the positive port D+ of detection of charging unit 402 and detection negative terminal mouth the D- purpose being shorted be for
It avoids identifying that OTG device 401 does not enter charge mode and prepares to OTG device 401 in power management chip PMIC
In the case where being powered with data interaction, and the inspection for allowing power management chip PMIC to detect that only charging unit can just export
Positive port D+ and detection negative terminal mouth D- signal are surveyed, on the other hand, thinking according to an embodiment of the present invention only need to be by modifying power supply
The software interpretation logic of mono- side of managing chip PMIC is designed and is detecting that OTG equipment accesses mobile terminal and the OTG is set
When for being provided with the access of USB charging voltage, charging according to the charging current and voltage set as mobile terminal, can be realized and moving
The charge function of dynamic terminal side.
Optionally, the OTG equipment has the Type_C interface being connected with mobile terminal.Type_C interface is mobile at present
The more general data-interface that terminal uses, the embodiment of the present invention is also not necessarily limited to using Type_C interface, all to meet USB work
The interface form of mode.
Optionally, in the case where the OTG equipment accesses mobile terminal, the OTG equipment is provided with for mobile terminal
The data interaction of line function of surfing the Net.
The embodiment of the present invention can only realize single wire networking function or charging function in synchronization relative to existing
For the OTG equipment of energy, while user's demand parallel for the wiring logging-on function of used mobile terminal and charging is met,
It is greatly improved the use of the user experience.In addition, since the type of current OTG equipment is diversified, present invention reality
It applies the OTG device 401 in the OTG equipment of example and is also not limited to and provide the data interaction function of wiring logging-on function for user, such as：Also
The OTG equipment of external memory space can be to provide, as long as OTG equipment can be connected by the operating mode and mobile terminal of USB
Corresponding data interaction function is connect and provides, then combining the charging unit having in OTG equipment in the embodiment of the present invention, just
It can realize that the data interaction of charging and various functions is parallel simultaneously.
Optionally, in the case where the OTG equipment accesses mobile terminal, the OTG equipment provides number for mobile terminal
While according to interactive function, charging unit 402 is for charging to the battery of the mobile terminal, and the charging unit is also
For powering for OTG device 401.
In embodiments of the present invention, when the mobile terminal in the OTG equipment and the embodiment of the present invention is used cooperatively, not only
The data interaction for the various functions that can be provided to mobile terminal is charged parallel with to mobile terminal, and since the OTG is set
Standby inside has charging unit 402, is powered without the OTG equipment of the mobile terminal to access, but passes through the OTG
Therefore the charging unit 402 of equipment itself, can also be saved simultaneously with powering for the OTG device 401 inside the OTG equipment
The power consumption of battery in mobile terminal.
As shown in figure 5, second embodiment of the invention proposes a kind of mobile terminal, including：Power management chip 501 and battery
502, wherein
Power management chip 501 has detected that OTG equipment accesses mobile terminal and the OTG equipment is provided with for working as
When USB charging voltage accesses, the USB charging voltage is linked into inside mobile terminal, and open reduction voltage circuit and close liter
Volt circuit, to use the USB charging voltage to charge battery 502.
Optionally, power management chip 501 are specifically used for：
In the case where the mobile terminal is connected by Type_C interface with the OTG equipment, the Type_C is detected
Whether one of two rotations drop-down current potential port CC1 and CC2 of interface connect with the corresponding port CC of the OTG equipment
And pull-up bleeder circuit is formed, if so, being determined with OTG equipment access mobile terminal, otherwise determine that no OTG equipment access moves
Dynamic terminal.
It is described herein once using Type_C interface, existing mobile terminal identification charging equipment and OTG
The principle of equipment is as follows：
As shown in fig. 6, there are one CC signal pins of design in the inside when external data line plug design, and the signal pins are being filled
VBUS is connected to by a 56K Ω pull-up resistor inside dateline, the female of Type-C interface is placed on mobile terminal, in order to support
Positive anti-plug, there are two CC pins, i.e. CC1, CC2 for female interior design.When external male connector is inserted into female, male connector CC pin can be with
Some pin in CC1 and CC2 in female is shorted, and CC1, CC2 in female are connected with power management chip PMIC, CC1
With changeable pull-up resistor and pull down resistor are designed with inside the PMIC of CC2, if it is external without insertion when if internal CC1 with
CC2 will be in poll detection external charging equipment and OTG equipment, it is assumed that male connector CC and female CC1 is shorted, due to external male connector
There is 56K Ω pull-up resistor in inside, and when PMIC inner wheel rheology changes to CC1 drop-down, composition circuit will be pulled up with external male connector
Pull-up bleeder circuit is formed, the formation of the access can inform that PMIC makes to form access inside VBUS and mobile terminal, to pass through
BUCK circuit, that is, reduction voltage circuit inside PMIC carries out charging operations, and charging is completed；When being inserted into OTG equipment, such as flash disk turns
Wiring etc., the male connector of the male connector and charging data line of OTG equipment have one to fix resistance the difference is that the male connector of OTG equipment designs
The pull down resistor of value, and the not 56K Ω pull-up resistor in the male connector of charging data line, inside the PMIC CC1 or CC2 in turn on
When drawing, one in CC1 or CC2 will just will form access with the pull down resistor of OTG equipment to form drop-down bleeder circuit,
Once detecting the high drop-down bleeder circuit and being believed that there is the insertion of OTG equipment in outside, the power supply of OTG equipment is mentioned by mobile terminal
For since cell voltage is not enough to provide the work of OTG equipment, this just needs the BOOST circuit i.e. booster circuit inside PMIC
OTG equipment operating voltage is provided, the work of BUCK reduction voltage circuit and BOOST booster circuit inside certain PMIC can be by software
Control.
